Oops after 30 days of uptime

Hello,
my home router crashed after about a month. It does this sometimes but this
time I was able to capture the oops. Here is the result of running ksymoops
on it (took a photo of the screen and then manually converted to plain-text).
Does it look like a bug or something other?

ksymoops 2.4.11 on i486 2.4.31. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.31/ (default)
-m System.map (specified)

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 c2000000
*pde = 00000000
