| Why is your kernel tainted?

As your request I have reproduced the oops without alsa and
webcam modules loaded in:

http://gzp.odpn.net/tmp/linux-pppoe-oops/dmesg-stock-2.4.22-rc2
http://gzp.odpn.net/tmp/linux-pppoe-oops/ksymoops-stock-2.4.22-rc2

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.
