After half an our of not playing with my linux box i get the following
"oopses" (only one is traced down a little) when calling a rsh from the
sunos-4.1.3 box nearby (telnet to the linux box before rsh avoids the
oops).

Here is what happened after the first oops and what syslogd and klogd
dont catch:

kfree of non-kmalloced memory: 0017cb30, next=00000000, order=0
kfree of non-kmalloced memory: 0017cb20, next=00000000, order=0
kfree of non-kmalloced memory: 0017cf54, next=00000000, order=0
idle task may not sleep
idle task may not sleep
idle task may not sleep
idle task may not sleep
idle task may not sleep
Code: 89 4f 04 8b 90 08 0d ..... (sorry).

Here is what i found in my logfiles:

Here is what /sbin/ksymoops produces:

Trace: 10a42d t handle_bottom_half+d/20

ksymoops itself produces

Oops! 182105c +182105c/0
Oops! 182105c +182105c/0
Oops! 182105c +182105c/0

on stderr.

Hope all this helps!
