KERNEL BUG: 2.4.22 processes occasionally segfault, kernel crashes, machine reboots
From: Dom
Date: Tue Dec 30 2003 - 14:10:16 EST
[1.] (seemingly random?) processes occasionally
segfault, kernel crashes, machine reboots
[2.] This particular time I was running oggenc on
bunch of .wav files, and the machine froze and
rebooted. When it came back up, I found the kernel
error message in syslog. I have had this happen once
before. I woke up in the middle of the night to hear
the sound of my floppy drive whirring during the POST.
I thought I was rooted or something. The box was
playing mp3's in xmms (so maybe its a float thing?).
The system is debian woody with a stock 2.4.22 kernel,
non-smp. NOTE - it DOESNT say OOPS in the logs, but I
did the oops-tracing anyway. It says 'kernel BUG at
memory.c:377! invalid operand: 0000' NOTE: I'm not
subscribed to the mailing list, if you want me to run
some tests or something please email me directly. I
dont know if this still happens in 2.6 or not,as I
havent had a chance to test it on this box. (if the
stuff below is mangled because of yahoo mail, let me
know and ill resend it nicer)
[3.] reboot, kernel, memory.c, oggenc, wav
[4.] Linux version 2.4.22 (root@localhost) (gcc
