PowerPC :: Random Kernal Panics QuadCore G5?
Dec 17, 2009
I've searched, but I haven't found any info on a situation like mine. I have a 2.5ghz Quad Core G5, it is outfitted with 4 gigs of ram and 2 500gb HD's. Everything was purchased in December of 2005. Over the last 8 months or I have been getting random Kernal Panics. Sometimes the machine will be sitting unused for hours and then I'll come back to it and it's locked up. Other times do not seem to have any pattern, it can be with multiple programs open, just safari, or FCP. The machine always starts right back up with no problems and typically continues to operate for hours or days before reoccurring.
I did the hardware check, and everything tested good. I switched to blutooth keyboard and mouse, and have disconnected all USB devices.I don't seen any signs of leakage.I am pretty much to the point that I assume the logicboard is bad. But I don't really know how to confirm this.
Being that the machine always starts back up and never has problems consistently I really don't know what to think. I wish it could be solved with replacing the ram and/or hard drives. But I just don't know how to determine the actual problem. All I have read is a lot of speculation.

I've been noticing that my early 2008 quad mac pro has been having more frequent kernal panics and is pretty random.I've also noticed that my video card fan(ATI Radeon HD 2600) has been reving up and down and has been more noticeable.Could this be related? Do I need a better card?

I got a new macbook pro a week ago. The first time I shut the machine down it experienced a kernel panic right after I selected to shut down the computer. Programs randomly crash while I am using the computer. The apple store said that crashes are most likely due to CS3 because it was not properly updated for the system, so they installed the CS3 updates. The next time I used the machine after installing CS3 updates, it experienced another kernel panic upon shut down. I would like to hear about known issues with the Summer 09 macbooks. I am trying to determine if this is a hardware, software, or an OS issue.

I have experienced these kernel panics lately, at completely random times, I don't know what the problem is. All I really have so far, is the panic.log.
My specs are:
Powermac G4 MDD 2003
1gb ram
80 gb hard drive
1.25GHz PPC G4

However Safari is causing all kinds of hangs restarts kernal panics overheating with my machine and yet if I use google chrome for the exact same web sites these same problems are not present. I much prefer to be able to keep using safari and I realise that I haev not got the most up to date software since Lion is not supported on my machine but it is as up todate as snow leaopard allows.
I also realize that a more than 5 year old machine is doing very well especially since it is rarely off. It has outlasted 2 timecapsules and countless airport express but the anomyly between 2 browsers is weird. I doubt this has a solution but maybe the odd apple tech who read this might find it a challenge to know why one browser causes heart issues but another doesn't.
Info:
Mac OS X (10.6.8)

my late 2006 macbook running 10.4.11 has been acting very strange since yesterday. first, it freezes while i'm recording something off of isight and i have to restart. works fine for 30 minutes until it randomly restarts (probably due to heat) and takes me two reboots and some time to fix it (i have to put an ice pack to keep it cool). then later in the night, it randomly restarts again and takes two reboots to get it back. then in the past hour, the screen has frozen, it went into a kernel panic and it randomly restarted again while i was trying to post this the first time. and also, it's been running very hot despite having no applications running.

I am having serious issues with my Apple PowerPC G5.. Its the 2.5 Dual Processor version of early 2005 running os x 10.5.8, i have installed; 2x500gb hds along with 4.5gb of ram... Ok now heres the problem, yesterday i came across an app called "CHUD" this apparantly was developed to help speed up an OS X system, so i downlaoded and began to install the parts to the app suite, after installing 1 or 2 of the CHUD apps i came to Reggie SE, i doubled clicked on the install then my G5 decided to freeze, completley! I tried Force Quit and nothing happended, the system would not respond what so ever, so i left it for 30mins or so to see if it would figure itself out and it didnt so i had no alternative but to cut the power and reboot....
Now, after reboot, my G5 will boot up to the User login dialogue, once i enter my password the dialogue accepts my password and dissapears (astho it is logging into my account) but then the screen turns Blue and the system returns to the Username & Password dialogue box..... Also the fans within my system begin to speed up and dont stop for a while, almost sounds like my G5 Tower is about to take off!

i was doing research and this was apparently a very common issue in the final run of G4 ibook 1.33 ghz.Like i said, i searched and found threads relating to this, but i had issues finding whether or not there was ever a conclusion:My girlfriend has an effected ibook, which we wrote off 2 years ago as a bad logic board and it has just been sitting around collecting dust. A friend mentioned the logic board/airport card issue, so I am wondering, is there a fix?

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.

Yesterday a friend gave me a really nice 17" iMac G4 he was planning to throw out because it was having problems. I would really like to get this working and would potentially be willing to buy parts to repair it. I have a significant amount of Apple hardware experience, but would like to get the opinions of people who may be more familiar with iMacs than myself on these forums. The problem is that the computer has random kernel panics. Sometimes it occurs as soon as the computer is turned on, sometimes after it has been on for a few minutes, sometimes after a few hours. So far, I have replaced the RAM with known good sticks, have replaced the hard drive with a tested good one from my collection (and these were both upgrades to boot!) and I have re-applied thermal paste (Arctic Silver) to all key components (CPU, ends of heatpipe, GPU) but to no avail, I still have the same problem.

I recently dropped my 4 year old iBook G4 (while it was sleeping) onto a wood table from about a foot up. When I tried restarting it, I kept getting kernel panics. So I completely reinstalled the OS (Leopard). Now I can do most tasks on the computer, but I still get kernel panics on a regular basis. I think there is clearly a hardware issue, although there is apparently NO physical damage to the machine. There is nothing wrong with the hard drive, which is the only mechanical device that could possibly be damaged by a drop, right? Reinstalling Leopard didn't really solve the problem. (I'm looking for an Apple Hardware Test disc to see if that will help diagnose the problem...)
Here are the details for the kernel panic (after I reinstalled 10.5 -- I haven't updated to 10.5.6 yet):

I just replaced the HD in an iBook G3 I have laying around with a toshiba 40gb. The install went fine and I formatted it in disk utility using mac os x extended (journaled). I ran it for errors and it checked out fine. I also ran the apple hardware test CD and everything checked out there too. The problem is I am getting a kernal panic no matter what I do. I started off installing 10.3 and the first disc installs fine, but then when it restarts it gets an instant kernal panic. I tried 10.4 with the same results. Then I tried the 10.2 discs that the iBook came with and it would get the very last step of the install on the 1st disc and would not go any farther. It said "one minute remaining" for over an hour.
I have taken a picture of the error log that shows up and you can see here: The top line got cut off but it says "panic(cpu 0): Unable to find driver for this platform: "PowerBook4,3" Like I said, everything checks out hardware wise and i have tried three different versions of OS X.

I recently bought a refurb iMac G5 with Os 10.4.11 - It has worked fine and now all of a sudden it will randomly go black as if hibernating and takes a few moments to come back on. It doesn't do it often, usually when I'm playing a video clip on the web for some reason, but not always.

My girlfriend has a 17" G4 Powerbook - she recently bought it second hand. It's one of the late models, with a 1.67 GHz processor and 2GB of RAM installed. It runs like a dream, except for one thing - it has a propensity to freeze occasionally. They're not kernel panics - they're hard freezes, where everything locks up completely. Can't move the mouse, can't force quit, nothing - the only thing to do is switch off and on again. I've looked through the logs and can't find any crash reports, so I'm at a loss to what's causing this. The only lead I have is that it only seems to happen when the machine's running on battery - it's never frozen when the power cord's plugged in. I thought it might be overheating, but it froze this morning after only 5 mins of use, so now I'm stumped.

My iBook G4 randomly locks up. No kernel panic message. It is as if there is a pause button that is getting pushed on the screen and when it locks up if it is playing music it plays about 1 second then repeats.it makes it take longer to lock up but it still locks up. I have tried bigger shims and that does not help. If I try to install Leopard on the iBook it doesn't even make it 25% before locking up.

I have a 15" PB Aluminum 1.5ghz with 1GB of ram. Just bought off a friend and when I did a fresh erase and install of OS X 10.4, repaired permissions and rebooted I get the kernel error telling me to hold down the power button and restart. So I did this and when it restarts I get the grey apple background with a load of writing all over it. How do I try and figure out what is causing the problem. I also ran tech tool pro from the DVD and that says everything has passed such as processor, memory etc

I have a 1.8Ghz dual processor G5, 1GB Ram, 80GB HDD, with OS X 10.4.7 installed and all current updates, and today I was working on it and the fans on it slowly started speeding up, and then everything on the screen disappeared and a mesage appeared stating that a restart was required. After restarting everything seems to be working fine, but I'd like to know if this is a fluke or if I have a serious problem.

Recently my job gave me this laptop that I think from what teh net says is a Titanium model. They told me it was dropped and the screen never worked. The thing is the screen kinda works, well the top 1/3 Horizontally of the screen shows the desktop and what not. The 2/3 of the monitor shoes a vertical pinstripe randome colors. The thing is I dont have the charger and I cant take a photo of it. I am wondering if its worth putting money in this laptop. I did while it worked hooked it up on external monitor, overall it works fine. My brother told me to ebay it and use the money for a Mac book. I just want opinions to what to do. I feel since theres still image showing on the screen may be just a broken cable or loose.

Now that Macs are starting to come with 64-bit kernal enabled by default (new 2010 Mac Pro, Mac Mini Server) how does that affect running applications that need Rosetta, such as MS Office 2004?

Over the last week I've had 2 of what I have now discovered are called "kernal panics". I've had this SR 2.2 for about a year and a half. I had one prior to installing SL last week 1 this week after installing SL. Other than the "You must restart your computer" message following the crash I've not noticed any other problems. I have not installed any RAM or other hardware. I've pasted the kernal panic report with the hope that someone might be able to help decipher what it means and what the issue might be.

I've written recently about my kernal panics on my imac g5 I reinstalled the original software and moved on to Tiger and it says "cannot install this on this computer" I have installed it before, it is my software bought free and clear. I don't know what to do. My son's college papers are due and we cannot get on the sites because our flash/etc. is not updated. I am now at 10.3.9 (I go to "about this mac", more info, and my system overview app will bounce on my tool bar and not come up.) I dont know what's going on. My hardware tests all came out clean.
