Hi, this oops seems to occur after about 5 days of uptime, the current
one occured after 7days.

Also, I'm not subscribed so please CC me on any queries.

Thanks.

ksymoops 2.4.9 on i586 2.4.23-pre7.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.23-pre7/ (default)
     -m /boot/System.map-2.4.23-pre7 (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 NULL pointer dereference at virtual address 00000004
