kernel oops, netstat -a

From: Lawrence Walton (

Hi I got a oops from netstat -a today, seems innocuous, and repeatable.
Happens on both stock 2.5.74, 2.5.74-mm1.

ksymoops 2.4.8 on i686 2.5.74. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.5.74/ (default)
     -m /boot/ (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
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
Unable to handle kernel paging request at virtual address 3ddcd9ae
