    I'm trying to understand why my 3 month old iMac 27" keeps displaying the Kernel Panic message. Took the machine in to the Genius bar yesterday and they suggested re-installing Lion would "definitely" fix it. Re-installed Lion and again today the Kernal Panic message appears, here is the log:

    Can anyone make sense of what is causing the issue?

    Have you recently changed any hardware, such as your hard drive or RAM?

    Not to hijack this thread, but....

    I bought an i7 3.4 27" iMac about a month ago and love it, only I upgraded to 10.7.3 about a week ago, and for the third day straight, I've received a kernel panic. I can copy & paste the log in -- the very first extension in the backtrace is as follows:

    Kernel Extensions in backtrace:
    com.apple.ATIRadeonX3000(7.1.8)[

    ... but I don't see that in the OP's log. Question to the OP regardless: did you recently upgrade to 10.7.3, and then the kernel panics started happening? Or have they always been happening?

    I'd concentrate on :

    com.AmbrosiaSW.AudioSupport 4.0
    at.obdev.nke.LittleSnitch 2.4.4

    What kind of USB device are you using that utilizes Ambrosia ? If any.

    Little Snitch might also be causing it.

    They had some kernel panics in an earlier version. Perhaps you found a bug in their latest version.

    Have you verified your booting disk is not corrupted via Disk Utility?
    From that information I can think of a filesystem corruption.

    I have upgraded the RAM quite significantly, from 6 to 12GB via Crucial.

    ----------

    I did upgrade to 10.7.3, the installation was corrupt and I have had a whole boatload of trouble since then. The kernel panics have only occurred since the upgrade (as well as a whole host of other issues).

    ----------

    I have two external USB hard drives (1TBs) but I don't believe either of them use Amborsia. I also have a Wacom light pad connected via USB. The only software I have from Ambrosia installed on the mac's HDD is Snapz Pro X.

    ----------

    Disk Utility doesn't bring up any errors when verified or repairing permissions, confusingly.

    A simple thing to try is put your old RAM back in and see if the kernel panics stop. If they do, you may have faulty RAM.

    You don't have to verify the permissions, but the disk itself.

    I still have the original Apple RAM installed, as well as additional Crucial RAM, for informations sake. It's also been suggested the problems could be caused by Little Snitch or Snapz Pro, so it appears I have a few places to start.

    The annoying part is the kernel panics are damn near impossible to 'create' so you think it may be sorted and then - bang - one comes out of the blue!

    Try running for a while with only the original RAM installed. I know what you mean about intermittent problems being harder to diagnose. I really doubt Little Snitch or Snapz Pro could be the source of your problems. Be sure you have a current backup of your hard drive, in case the drive is going bad.

    I don't know if this is relevant to the issue, but I just opened iTunes to put a file on my iPad and iTunes has removed most of my music collection (its on a hard drive so it's not gone, just removed from iTunes) and it appears to have been 'reset' as all my playlists etc are now missing. Of 10,000 (approx) songs I now have just 326 showing and all settings have defaulted.

    May not be relevant, but worth sharing.

    What version of Snapz Pro X are you using ?

    Also Disk utility won't do much. I'd look in the console for crashes and see what may be causing it.

    The memory could be a cause. Make sure it's sitting properly and/or put the old memory back in and see if you get another panic.

    The iTunes thing. Are the files on an external USB drive ?

    If so it could be the controller for the drive.

    If your iTunes Media folder is on an external drive that isn't properly mounted at the time you launch iTunes, you'll get the exclamation marks next to songs, but your playlists, etc. will be intact. Simply mounting the drive and relaunching iTunes will fix that. If, however, your iTunes Library files are on an external drive that isn't mounted when you launch iTunes, iTunes will create a new library on your internal drive that won't have your playlists, etc. If that happens, close iTunes, then hold the Option key down while you relaunch it, which will give you the opportunity to select the library that's on the external drive.

    When troubleshooting any problem, it's best to eliminate as many possibilities as you can. Disable or shut down Little Snitch and any other non-essential apps. Go back to only the original RAM. Keep things as simple as possible. Then, if you don't have any kernel panics, add the RAM. Track that. If no kps, turn on Little Snitch. Track that. Continue until you find the culprit.

    The hard drive appears in the finder sidebar and is active and connected, yet iTunes acted all screwy. I'll give the option-key tip a try.

    ----------

    Sound advice indeed, this is a great starting point.

    Does that external hard drive have Firewire AND USB ports ?

    It might be going to sleep and when the system tries to read/write to it you get a panic.

    Reason I say this is your first panic had the USB driver listed 3rd and this time it had the Firewire driver listed 3rd.

    Did you happen to switch from a USB cable to a Firewire cable ?

    I forgot to mention I have a 3rd drive connected via Firewire which acts as my Time Machine. I do tend to have issues with that drive not appearing after the machine is asleep etc.

    The two external hard drives I have with files and documents are connected via USB and I don't ever fuss them etc. Hope this helps. Thanks for being so helpful thus far.

    Sounds like the Firewire drive is the culprit. If you have problems with it when you computer goes to sleep and time machine tries to do a interim backup it won't see the drive and possibly cause a panic.

    Sorry, I can't decipher your log, but I can tell my own story [hopefully that might help someone reading :eek:] Anyway, about a month after buying my 27" iMac i started getting kernel panics every time I started it [either immediately or soon after]. This happened 6 or 7 times in two days. I was convinced my iMac was a dud and was about to return it, but I decided to first quickly search online [using my macbookpro]. While doing this I came across a number of threads on various websites about low battery in trackpads causing kernel panics. My battery was about 10%. I changed it, and haven't had a kernel panic since [about 3 months now]. I don't know if it's just a trackpad issue, or if it affects the wireless mice as well. But if the batteries are below 20%, it's best to change them just to rule this out as the cause.

    Or better yet, do a hardware test. That's how i verified my issue with kernel panics wasn't hardware related. (It was actually a Chrome issue AND a kernel panic issue, but i didn't figure that out for months)

    have you tried going to about this mac under apple in menu and looking for any attached hardware etc with a serial number that matches any of the set of numbers above, or looking for a app that has a reg code that matches. It might find the culprit.

    it appears that the KPs were probably caused by these third-party kernel extensions. Remove them and see if KPs will go away.

    I went through the system information and nothing matched that UUID for hardware (memory, usb HDD or firewire HDD). Is there a way I can access or search for app reg. codes?
