As requested by a couple of people off the list, here is the output of
ksysmoops. Sorry I didn't provide this earlier.
I suspect it's an interaction with Andre Beck's isdn_lzscomp module,
although it was happy with previous kernel releases. Incidentally I'm still
using isdn from ftp.suse.de not the ac12 isdn code.

-----------
Options used: -V (default)
-o /lib/modules/2.2.10-ac12/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)
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.
