2.4.18 oops.

Below is an oops that occurred for no immediately apparant (to me)
reason.
The CPU was not too warm, overclocked, ...
Athlon 550, 196Mb RAM.
I was probably running very low on memory at this point.
I was not paying attention, so can't vouch for the order in which
these happened.
the last command I remember issuing was lspci -n, as I wanted to find
out the revision of the bt848 in my hauppage card, to try to work out
what might be causing it to flicker a bit.
A large process wanting memory seems to have been killed around this time,
as I had forgotten to activate my secondary swap partition.
I had within the last few seconds switched out of x to run lspci.

I did not unload any modules after the oops, before running ksymoops.

ksymoops 2.4.3 on i686 2.4.18. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.18/ (default)
-m /usr/src/linux/System.map (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.
