Couldn't do anything to get it back, had to finally reboot (even tho
the machine was up and fine on the net). ;(
Anyhow, hopefully the oops is usefull to someone:
Unable to handle kernel NULL pointer dereference at virtual address 00000021

and when run thru ksymoops:
Options used: -V (default)
-o /lib/modules/2.2.4/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)
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.
