[1.] System crash killing idle task

[2.] I returned home after 8 hours of disuse to find the system crashed
with various jibberish on the screen. As I could get no response, I could
not copy all of the information I saw, but wrote down the final lines
after the screenfull of jibberish:

Code: 89 10 b8 01 00 00 00 c7 43 04 00 00 00 00 c7 03 00 00 00 00
Aiee, killing interrupt handler
Kernel panic: Attempted to kill the idle task!
Interrupt killer - not syncing

[3.] kernel crash killing idle task

[5.] I did not see an oops message. I have logged the output of ksymoops
anyway, so if you need this information please notify me.

[7.6.] No SCSI in system

[7.7.] I am unaware of any further information to look for.

As you can see by the kernel information, I have compiled this kernel only
a few days ago, but have been running 2.2.4-test12 for a little while
longer than that. I had recompiled in an attempt to get sound working
properly. This is the first time I have seen anything of this magnitude
happen.

Thank you,
Jon Eisenstein
