    Hello all,

    I've been encountering these panics very frequently. I think it mostly happened when I tried to sync my iphone to my itunes.

    Could this be hardware or firmware error?

    My suspicion is that my USB are faulty.

    Can someone identify from the error message below, what the problem is?

    Thanks alot!

    You can confirm the presence of a hardware issue by running hardware test which is included on the discs that came with your computer.

    I don't think you have a hardware issue it looks like it is a kernel extension issue. If you look at the back trace it says:
    Kernel Extensions in backtrace (with dependencies):>0xffffff7f810adfff

    I would run the following terminal command:
    at the prompt type exactly:
    sudo kextload -t /System/Library/Extensions/IONetworkingFamily.kext
    at the prompt type your password and wait for the output if could take a while.

    Perform the same for IOUSBFamily.kext

    Check what the output is: if the output is normal it will say that it can load if it has issues it will tell you. Post results.

    Hi MacForScience

    Thank u for the prompt reply.

    I typed the command into terminal, but I got this instead:

    Notice: -print-diagnostics (-t) ignored; use kextutil(8) to test kexts.

    Is there another command I must type? Sorry, I'm not good at command lines.

    They must have changed the command on 10.6. Change the command to the following:
    sudo kextutil -t /System/Library/Extensions/IONetworkingFamily.kext do for both .kext mentioned in my previous reply.

    Sorry about that I was not aware they changed that.

    Hi MacForScience

    I got the following replies:

    The booter does not recognize symbolic links; confirm these files/directories aren't needed for startup:

    Not sure what went wrong here...

    It is a USB device causing the problem. Try it without any USB devices connected to it and then Reset Your PRAM. Then try it without any USB devices to see if the Panics clear up.

    You did it right. You can try the PRAM reset I doubt it will work. You need to replace the two kext files. You can find them on the DVD.
