Subject[2.4.22-pre10] Kernel BUG at vmscan.c:358!
Date
Hi to all,
I know this kernel is a bit outdated (2.4.22-pre10) but just in case it is
interesting for somenoe I'm mailing the ksymoops output. Note that in the
logs there are various consecutive oopses and in this email I'm attaching
just the first one for not wasting bandwith. Of course if you need the full
log (~500 lines) just ask.
And please CC me as I'm not subscribed in the ML.

decoded oops follows,
Bye
fredi

ksymoops 2.4.8 on i686 2.4.22-pre10. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.22-pre10/ (default)
-m /boot/System.map-2.4.22-pre10 (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.
