| |
I'v crashed 2.3.9 several times the last day or so. Most of the times it happend while doing a simple grep in a file. It's very hard to get usefull info as it usually just locks up X completely or reboots. Never anything in the logs, but I finally got some output to the console that I could write down on paper and feed ksymoops. I couldn't see the whole dump, as it scrolled to fast and I couldn't scroll it back. But the trace just seemed to repeat itself so maybe I got it all.
So, usefull or not, here goes:

Aiee, killing interrupt handler Kernel panic: Attempted to kill the idle task!
1 warning issued. Results may not be reliable.
I then pressed ctr-scroll-lock (or something like that) and this is what I managed to write down before the screen went black:
Unable to handle kernel null pointer dereference at virtual address 0000006a current->tss.cr3 = 00000666, %cr3 = 00101000 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<c0111e86>]
About the EIP line, ksymoops says: >>EIP: c0111e86 <show_task+c2/1a8>
About the system:
64MB of memory, never had any crash with 2.2 and 2.1 kernels.
