I'm getting Oopses at reboots while pppoe module loaded.
Linux 2.4.22-pre* and -rc*
pppd version 2.4.2b3
The ksymoops output attached, more details at
http://gzp.odpn.net/tmp/linux-pppoe-oops/
ksymoops 2.4.9 on i686 2.4.22-rc2-gzp1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.22-rc2-gzp1/ (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.

Why is your kernel tainted?
Are you using stock 2.4.22-rc2 or do you have any additional
patches/modules running?

Stock 2.4.22-rc2 with alsa, and I'm using a binary only
module for my webcam from http://www.smcc.demon.nl/webcam/
BUT, I'm getting the oopses *without* the module loaded in.
Its loaded at startup, thats why tainted later.
I can reproduce the oops all the time, with or without the module.
