Found this in dmesg today...
Default RH7.2 kernel
I have no idea how/what triggered it, so I doubt trying with a later
kernel to see if it happens again will help (it came after almost 10 days
of uptime). Just posting this on the off chance it may be an undiscovered
bug.
ksymoops 2.4.1 on i686 2.4.7-10. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.7-10/ (default)
-m /boot/System.map-2.4.7-10 (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.
