I've also posted a message with the same error - different
address though. I did not receive a reply from anyone at all
though so I don't know if it was received. Here is my syslog
entries. This is kernel 2.0.30. If any more info is needed, I'm
expecting someone to ask for it because I'm not going to spend 45
minutes creating a full bug report - to not even know if someone
received it.

Please let me know if more info is needed.

Once again, this was on a linux 2.0.30 kernel. The system was
not deadlocked, but init had died so I had to hit the switch.

Take care.
