    Hello everyone, I have the same problem with my imac too... I know it is old and I have already purchased a new one, but this one is my first apple computer, and I cannot throw it away so easily :( ... So, please if anyone can read above the last panic report I got and understand what's the problem, leave a message here explaining to me what it is and if it can be fixed (without spend a fortune of course)

    Interval Since Last Panic Report: 28129 sec

    This is the same model iMac I have.

    Mine began having kernel panics a couple of years ago, which were caused by the graphics card. Sadly, on this model iMac5,1 the ATI Radeon X1600 is an integral part of the motherboard so it's only replaceable by replacing the entire motherboard.

    However, what I was able to do was disable the ATI kernel extension for this GPU which prevents the kernel panics. The iMac has since run for a couple of years without a kernel panic.

    HOWEVER, the drawback with this is that any video playback or games are unusable, since you lose video acceleration. My machine happily records DTV using EyeTV and compresses them to .avi without problems - it just can't play them without dropping frames.

    In your kernel panic report, there are two offending kexts. One is IOSurfaceAPI, which according to Apple is:

    and the ATIRadeonX1000 kext - the driver for the GPU.

    Removing just the ATI driver should do the trick. Boot into 'safe mode' to prevent the machine crashing to move the extension to the desktop using terminal and your administrator password:

    sudo mv /System/Library/Extensions/ATIRadeonX1000.kext /Users/YOURUSERNAME/Desktop/
    Then reboot normally.

    Sadly, this is the best you can do, without replacing the motherboard. Of course, how you will buy a motherboard that doesn't exhibit the SAME fault, is the burning question. It may not be possible. :eek:
