Hi Mike,
I think normally it would have, for a tempdb as that is rebuilt from model. For a regular database, the 6103 would probably have been fatal to normal recovery unless it was somehow a transient error.
I think what may have happened is someone used dbcc dbreboot to try to shutdown and restart just the one database instead of the whole server but didn't complete the reboot step, and the whole server was then rebooted instead.
