Mac Pro :: Repeated Kernel Panics / How To Avoid It
Feb 20, 2009
I began having freezes unrelated to any new software or behaviors. The hardware check showed no problems with the hardware or memory, so I cleaned out the inside of the computer, used Disk utility, AppleJack, Mac Janitor and reset p ram (all said it was OK, then the freeze came back), and finally zeroed the hard drive and reinstalled OSX.
It was stable for a few weeks then the freeze happened again followed by repeated kernel panics. I went thru all the steps above again but finished with an archive and install and created a new user admin account. Until this point the freezes and KP were on all three user profiles. But now this new user admin is fully functional while the others are still messed up.
I've been having repeated kernel panics for a little over a week now. I've run disk utility, tech tools, the disk utility on the installation disk, remember ram test, installed a virus checker, reinstalled (archive/install) mac os x. I am not receiving any errors in the tests, but I am still having kernel panics. They always happen when I am on the internet, not immediately, but I'd say about 20 minutes or so into a session. I first started having the panics when I clicked on a link from someone's facebook page and a kernel panic immediately popped onto my screen. I've been having them ever since.
I have a 15 inch 2010 MBP. When I got it, I migrated all my info from my previous MB. About 4-5 months into using it I started having issues w/ Kernel Panics. I did upgrade the HDD and RAM but the Kernel Panics happened before all of that. I took it to the Apple store and they ran some test on the hardware and software and said they couldn't find anything. Their advice was to just do a clean install. I wanted to avoid doing a clean install on all costs. Anyhow, I said what the who last night and backed up important files and did the clean install,
I have to say that the computer feels much more stable now. I was having a lot of little issues w/ Snow Leopard prior to the clean install. Most of that probably comes w/ me playing around w/ settings a bit too much. Also, I'll admit, I do torrent some software. In my opinion, thats what caused the kernel panics. Only time will tell if I continue to get kernel panics even after a clean install, but I think I'm good to go. So, do you guys prefer doing clean installs or just migrating your data? When Lion comes out, will you clean install or migrate to it?
I have a G5 tower and randomy since last night my computer did that whole kernel panic thing then i restarted... sometimes it didnt boot up the computer just sat there. Other times it loaded and the computer would work for sometimes 5 to 30 mins before freezing again. What do you think it is?
I am running a quad core G5 PPC. I updated to 10.5.1 last week when it was made available and had no problems until yesterday. I tried to empty the trash and immediately had a kernel panic. I restarted and that is when the problem became more apparent then a simple restart! The Kernel Panic continued to repeat itself on the startup screen. I called apple support and went thru all the steps with them including trying to boot from the OS X 10.5 disk, in safe mode, as a target, trying to reset the (I guess I forgot what we were resetting but I was told to hold down Apple-R and Option-P) as well as opening the case and holding down the small button underneath the RAM. Anyway, nothing worked. Even in target disk mode, it made my G4 Powerbook running as the main pop up with a kernel panic! I cant get to the finder to see what the kernel panic parameters are.
I tried to locate /Library/Logs/PanicReporter according to this link to no avail. I'm not happy with logging using verbose mode and having to retype it all up. I also don't have it in a network of macs to allow for this technique and I feel as if there's a pretty obvious way of capturing these reports that I'm missing.
I have had the Macbook air 11.6 for five weeks now and it has been rock solid except for a couple of kernel panics. Once when I first got it I got a kernel panic in Safari. I only use google browser now. I got a kernel panic two days ago. I went to open the lid and it did not come on. I found out there was a kernel panic. I am afraid if I take it to the genius bar they will have me reinstall the OS and add one app back at a time to see what is causing it but since they are so infrequent this is obviously not convenient. Also I have had my IMac 24 for three years and have tons more junk on it and have never got one panic.
Can kernel panics on one machine somehow cause panics on another machine. My situation, I recently started using a BC338 esata card in my mid 2007 MBP running Leopard. Never had panics before but since trying to use this card with an esata drive I've had 5 kernel panics. I also have a Mac Mini running Snow Leopard which has had two kernel panics during times when the MBP had panics. Can these be related? Before using this card, I never had panics on either machine?

From the log, can anyone tell me what's causing the kernel panic?
I am currently planning to upgrade my 2gb RAM and I heard that my model supports up to 6GB of RAM, hence I am planning to upgrade to that size cause Aperture uses lots of memory and I use Aperture a lot. I am planning to get it from here: OWC 6GB PC5300 DDR2 667MHz DIMM Upgrade Kit. Everything is cool and all until I find out that some users are having kernel panics on OSX 10.6 with 6GB RAM (which is what I am using). It is now 10.6.3, so anyone care to report if it is safe to use 6GB or the problem still exist?
I've been having a lot of Kernel Panics (you need to restart black screens). I've only just worked out that they almost always occur after the mac has been dormant. For instance, I'll leave the machine on (and the black screen/sleep mode activates instantly), after twenty minutes I come back to the machine, it comes back to life, but within a minute or so it crashes. This seems to be the pattern, it very rarely crashes mid-use. Safari is also nearly always loaded?
I have some problems with my macbook 4,1 (early 08). Since a few weeks I get sometimes kernel panics. Last night I had 7 kernel panics within 1 hour. Can anyone help me analysing these logs? memtest86+ doesn't show any problems after 8 hours.
I kid you not, ever since I updated 10.7.4 last night, I've had at least 3 kernel panics, plus it wouldn't wake up from sleep.
Sometimes it seems to crash for no reason at all -- the computer will just be sitting there and I won't be doing anything; granted, I'm sure a skillion processes are running, but no more than I would usually run.
Where are the pertinent logs hiding so I can share them with some wise soul?
Last week, after completely normal use, the computer booted up to a screen with the finder icon / flashing question mark. After a few more atempts to power up i started getting just the grey apple screen with spinning wheel and loud fans. I was advised by a friend to boot from the install DVD by holding alt when powering up. When i try this, after selecting the DVD from the boot up options, I get kernel panic and the message " panic: We are hanging here...". Then nothing.
I've been using my new Mac Pro with no issues for several weeks with the same hardware setup & OS all along. Suddenly I'm getting kernel panics. It happens when I startup from the system drive or from install disc. And sometimes when I startup it just hangs on the blue screen with no desktop coming onto the screen. It started happening after I did a Carbon Copy Clone of my system drive onto a firewire drive, & when I came back to my computer several hours later the screen was black & white stripes. I've been on the phone with apple care several times and even took my machine to the genius bar today where they recommended a stress test and said I would get it back in 5 - 10 business days (gasp!). Of course there were no kernel panics while I was there (for an hour, and at home I'm getting them every few minutes), so I decided to take it home & check it over myself in a process of elimination.
I've removed all third party ram, and have 2 hard drives installed - the system drive & the drive I use for time machine. The RAM is listed as OK in system profiler and the HD's are verified with Disk Utility - also disk permissions verified & repaired on the system drive. I have 2 Acer monitors - model AL2016W. I tried plugging in one at a time in each DVI port for a total of 4 tests - each with a fresh startup. There were no kernel panics. Then I plugged them both in at the same time, started up, & got the kernel panics. Tried this twice with the same results. With or without any applications open, it's the same. Within 2 - 4 minutes I get a kernel panic when both monitors are plugged in. Later, I got kernel panics with just one monitor connected. So my question is; What could be the reason it's getting kernel panics sometimes & sometimes not? As I said, nothing has changed in my setup since I got the machine - and everything was running fine since mid February.
During my testing I have these connections: One or two monitors. Power cord. Apple wired keyboard & mouse (these were not connected at the time this started happening so I have eliminated them from the possible source of trouble.) All bluetooth devices are powered off & no other external devices are connected. I just completed the Apple Hardware Test & it detected this error: "4HDD/11/40000004.SATA(0,0)" Does this mean there's something wrong with a hard drive? If so, which one?

I have become increasingly frustrated and angry at my MacBook in the last few weeks. Nearly every time I plug in a USB hub, I get a kernel panic. When I send the report to apple, this is what comes up near the bottom of the window:
Sometimes there's a USB HUB written in there. What is going on? I've tried switching from a rather generic hub to a Belkin one, and most recently I just plugged in my aluminum keyboard and immediately got a KP. They've been happening with regularity over the past while, all when I unplug or plugin my USB hub with an iPod touch, keyboard/mouse, USB drive and headset (though recently I've been removing peripherals). I'm about to do an archive and install (assuming my MB works long enough for me to download the combo updater) but want to kill this bug soon.
New to the forum and unfortunately with a problem. Just got a new Mac Pro 8 Core over the weekend and Im having unusually high number of Kernel Panics (more in a couple of days then I have for the past 10 years with my other macs). I have tried to see if anything in particular causes it (ie Programs that cause the crash, time intervals, etc) and nothing can be ruled as the cause at least not that I can notice. It has happened wile using PS (CS4), Aperture, Google Earth, Safari and just in sleep mode. Here is one of the Kernel Panics along with system info. ps. The Mac started kernel panics before I loaded two additional hard drives and the wireless card (pci express).

My computer is having constant kernel panics. I have had about 10 in the past 18 hours, and I am starting to freak out about it. Here is the info from the error report:
BSD process name corresponding to current thread: firefox-bin Mac OS version: 9G55 Kernel version: Darwin Kernel Version 9.6.0: Mon Nov 24 17:37:00 PST 2008; root:xnu-1228.9.59~1/RELEASE_I386 System model name: iMac5,1 (Mac-F42786A9)
The part that says BSD process name corresponding to current thread has changed every time. When I have apps open, it will read the name of the apps extension but if I don't run anything it will say "system kernel" or something.
I just had one and I am scared of it happening again all I way doing was youtube, ichat, and aim express then safari got buggy on me and beached balled me and all of the other apps were working then all of a sudden. Drop down gray curtain kernel panic I save the report.
The computer I am having problems with is a Mac Dual 2.7 Ghz Power PC G5 with 3.75 GB DDR SDRAM. Moved premises at start of year - had to have a new ethernet adapter card fitted but no problems for about 4 months. Then it started having Kernel Panics. It got to the stage where at one time it was 3 to 4 times a day. Took it to a local repair shop who put it on test but said they couldn't find a problem. Within 10 minutes of my switching it on it went again. They changed a memory board. Still no change. Changed Ethernet adapter card. Still no change. I have a print out of the latest system & console logs I can email if that will help an expert.
After some partition troubles I popped in my snow leopard disc and erased my HD. I then made a windows partition. Then, I tried to restore from a time machine back up I had. It finished restoring and said to restart, so I did. It doesn't get past the apple sign though. After the grey screen with and apple logo sit their for a few seconds it kernal panics. I can't get any farther than that. Should I re-restore or what?
i have a 2.2GHZ intel core duo 2007 MBP, which once ran Tiger and is now running 10.6.3I had the graphic card break down associated with such models, and it was replaced thanks to the extended care plan-I originally had 1Gig of ram, but 1st got an extra 2Gb of danelec ram, and finally another 2GB- it ran fine for a year or so-then I started getting these kernel panics, which seem to be ram related-on tiger- I changed the HDD, switched to snow leopard, and they continue, they're apparently RAM related, yet what is odd is that they can be reproduced with any RAM combination involving 2 sticks- the original apple 1Gb + any of the two GB ram sticks, the 2GB ram sticks together-- it's all the same, the screen goes grey and i'm told to shut down the computer
with one ram stick it works, apprently avoiding the issue-i've moved the ram around, checked the slots, reset the PRAM,yet the issue is still there.now i know that I should be using paired ram, and will do so in the next coming months when I can afford it- yet what has happened to make the make the MBP seemingly refuse two sticks of RAM when it didn't before ?I'd also need to know that this is not a logicboard issue if it's possible- the logic board was changed due to the NVDIA bug, so it's a year old or so-I'm running it on the 2GB danelec as I type, no issue, the samsung ram works as well, and so does the 1GB apple ram, in any slot, yet two slots of ram causes the kernel panic crash- the area near the ram slot also seems to get very hot
I've been getting kernel panics for a while nowand I did not install any new hardware or apps, so I decided to create a new account and I've been going strong for a week without any panics. I then decided to log back into my main account and after 2 days I got a panic. I always just use Safari 5 web this happens. I did not install any plugins prior to all these panics
Lately my iBook G4 with Tiger has been getting Kernel panics off and on. I have been trying to solve this problem and have been posting on the apple forms, usenet Newsgroups, and Yahoo Groups. I last had a Kernel Panic on July 11, but ever since last week have been getting them left and right. Here is my latest one.
