I got this oops on a computer nnig 2.2.7 SMP.
If you need any additional information, feel free to contact me.
Thanks,
Lucho
Options used: -V (default)
-o /lib/modules/2.2.7/ (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.
No modules in ksyms, skipping objects
Status: RO
Unable to handle kernel NULL pointer dereference
