I tend to get these after a few days uptime. This one locked X
hard, ping and ssh over net etc still worked ok.
Pretty standard x86 PC hardware.

ksymoops 0.7c on i686 2.4.5-ac13. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.5-ac13/ (default)
-m /usr/src/linux/System.map (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.
