Hi,
yes, i had to copy it from the screen. And if you look at the stack trace,
you will propably find it not very helpful. But it _is_ a problem with
the ax25-stuff. It happens some seconds after typing ifconfig ax0 down
if there are open ax25 connections. there is enough time to switch to
the syslog-console. About 2 secounds, then the Oops happens.
Here the ksymoops output (the defaults are ok).
-- snip --
Options used: -V (default)
-o /lib/modules/2.2.5/ (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.

2 warnings issued. Results may not be reliable.
-- snip --
There may be errors, since I had to write it down on paper and then
type it in again. ksymoops complains about module mkiss not exporting
symbols:
Warning in compare_ksyms_lsmod, module mkiss is in lsmod but not in ksyms, probably no
symbols exported
Don't know why.
