using kernel 2.2.10-ac12 I get an reproducible oops when I stop knfsd.
It's done by an /etc/init.d script which calls 'killall -2 nfsd'
(Debian 2.1 + a lot of packages from "unstable", knfs 1.4.6 but I checked
1.4.4 which shows the same problem) It started around 2.2.10-ac10. I
cannot tell it more precisely, sorry.
/etc/exports contains two entries. The oops doesn't occur with only one
entry:
/home pc1
/ pc2
(It doesn't seem to depend on the actual contents of the lines)
I'm sorry if this is a known problem. I haven't read the kernel list lately.
Greetings,
Ulf
ksymoops 0.7c on i586 2.2.10-ac12. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.10-ac12/ (default)
-m /boot/System.map-2.2.10-ac12 (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.
Warning (compare_ksyms_lsmod): module nfsd is in lsmod but not in ksyms, probably no symbols exported
