2.4.21-pre5 oops in mod_timer

[Rob Funk <rfunk@funknet.net>]

2.4.21-pre5 has been the most stable 2.4.21-pre yet for me (I haven't
tried the pre5-ac patches though), but after a week of uptime I got
this oops...


ksymoops 2.4.6 on i586 2.4.21-pre5.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-pre5/ (default)
     -m /boot/System.map-2.4.21-pre5 (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.
