iMac Kernel Panic

[AutumnSkyline]

So my iMac had a Kernel Panic, I would like to know the cause of it, and anyway to prevent these from happening in the future. I was restarting my iMac anyway, but it unsettles me that I had a kernel panic.

Please help, here is the report:

There's nothing here that is a real indicator of what caused it. Looks like it's unlikely that it was caused by software.

Unless this is a repeatable/consistant issue, I wouldn't worry about it. Transient KPs are not worth the headache.

Sorry to be harsh, but do you really expect that any of us here will be able to deduce anything from that log, even if we wanted to invest the time to go through it?

I can, and have. It's not that difficult.

For example, it's pretty clear where this issue is based:

Here is what is in the panic.log:

okay, thanks yellow, I was thinking it was a software issue, I was installing software, and I figured I would reboot. I installed it, rebooted, and before it shut down, the kernel panicked. So, thank you for your help, needless to say I trashed the software.

Neven, I have seen people post crash logs before, and people have figured out the cause of the issue, so I figured I would give it a shot.

Well, there's no assurances that it ISN'T software related.. but typically when it is, you'll see some sort of reference in the KP log that points to something other than random hexidecimal memory space. Of course, if what you installed had installed a kernel extension, all bets are off.

So, like I said.. it's all up to you in pursing the issue dependant upon how often it happens, or if it's reproducable.

So as long as we're talking about kernel panics, just over a month ago I got a blue screen of death on Windows Vista. I was just shutting down, it was taking a ridiculously long time, and then the screen turns completely blue. Looks sort of like the XP one(how can it look any different, it's just blue) but there was no text whatsoever. When I restarted my computer and got back to my desktop, it showed an error report titled "Blue Screen". Out of the 8 months that I've had Vista installed, that was the only time I've seen the BSOD.

Anyway, as long as your computer doesn't crash or kernel panic often, I wouldn't worry about it. Sometimes this kind of stuff can happen.

But if you do get a kernel panic often, the first place to check would probably be the RAM. Try taking out one at a time and leave the other inside the computer. That is if you don't have a Mac Mini.

what if we installed some software where everytime u boot you get the kernel panic, how woudl u resolve this problem? a total reinstall of tiger?

 

[DoFoT9]

^^ that would be a software related issue. most likely a full harddrive wipe and reinstall would fix it.

No. It would most likely be related to a kernel extension that the software installed.
Just boot into Safe Mode and remove the errant kext.
Problem solved.

For the record, I experienced two kernel panics within a day of getting my new Aluminum iMac last week. I had a funny feeling it was the Logitech Control Center software for my VX Revolution (which was the only thing different that I had installed compared to my old iMac)...and sure enough, since I removed it and replaced it with USB Overdrive, no more kernel panics. *Looks for wood to knock on...*

I love Logitech's hardware, but MAN do they SUCK at writing software.
