1. One line summary of the problem:
---------------------------
Oops during system shutdown while killing the server tasks.
2. Full description of the problem/report:
---------------------------
Oops during system shutdown while killing the server tasks. Looks like
`killproc' trying to kill `sshd'. I'm afraid I can't reproduce it since
it's the first problem after 10 days and about 30 system starts &
shutdowns with 2.3.99-pre6.
finished shutdown with `Magic SysRq key', no trouble
