Kernel panic Part 1

davidmorr

[This whole post is about 13000 characters. But when I try to post it, I get told "Message cannot exceed 20000 characters". Perhaps the admin needs to check the configuration.....]

I don't know if this was related to Sophos or something else, but.....

I had been running Sophos for around 24 hours, scanning my Time Machine backup disk. Then the machine just turned itself off. I was not using it at the time, except for listening to a podcast in iTunes.

Kernel panics are not something I expect on OS X. The last one I had was nearly ten years ago with OS X 10.1.

This is OS X 10.5.8 on an iMac 2.8GHz Core 2 Duo, 4GB RAM.

The panic report follows.

    Thanks for the logs David. From what you've reported, it looks like this issue isn't anything to do with the NTFS issues - so I think we can rule out that line of investigation.

    First thing to check then is if there are any associated crash logs that happened at the same time. If there are any, they should be listed in:

    /Library/Logs/CrashReporter/com.sophos.intercheck.*

    Secondly, the logs posted suggest that the On-access scanner was unable to load the Kext, so the next thing to check is the permissions on the Kext in:

    /Library/Sophos Anti-Virus/Intercheck.app/Contents/Resources/Sophos Anti-Virus.kext

    These should give:

    drwxr-xr-x  3 root  wheel  Sophos Anti-Virus.kext

    Please let me know what you find.

    David
