SubjectLarge trace of sched.c 505 BUG(), decoded

This bug was triggered by trying ctrl-alt-del for reboot in
test10-pre5. It appears to show schedule() getting stuck in
a loop with the stack growing unbounded.

Unfortunately, the module list and symbols are not exposed.
I don't know what had been unloaded before the bug
triggered. The initial module list shouldnt be too different
from the current:
ppp_deflate 40064 0 (autoclean)
bsd_comp 4320 0 (autoclean)
ppp_async 6480 1 (autoclean)
nfsd 68624 0 (autoclean)
lockd 50704 0 (autoclean) [nfsd]
sunrpc 59072 0 (autoclean) [nfsd lockd]
ppp_generic 13024 3 (autoclean) [ppp_deflate
bsd_comp ppp_async]
slhc 4688 1 (autoclean) [ppp_generic]
parport_pc 18864 1 (autoclean)
plip 11152 1 (autoclean)
parport 26240 1 (autoclean) [parport_pc
tulip 33904 2 (autoclean)

Unzipped, the trace is over 420k. The stack trace is
periodic enough that, bzipped, it is marginnaly short enough
for l-k.

Serial console is a very good thing :)
