Here is output from a second incidence of this bug. This crash occurred
just this afternoon.
ksymoops 2.4.11 on i686 2.6.18-4-686. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.18-4-686/ (default)
-m /boot/System.map-2.6.18-4-686 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Error (regular_file): read_ksyms stat /proc/ksyms failed
ksymoops: No such file or directory
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
1151MB HIGHMEM available.

This architecture has variable length instructions, decoding before eip
is unreliable, take these instructions with a pinch of salt.
