My Ubuntu box recently started hanging during reboot. It occurs during the "shutdown" process - before the machine actually resets (bios screen flashing by?). I have to force a shutdown with the power button in order to get out of this state.
Strangely, a standard shutdown does not result in a hang up, only a reboot does.
I haven't been able to identify any culprits by watching the output during the reboot. I've tried several of the items in this post to no avail. But I did notice in that post he mentions "The logs don't show anything unusual."
Are there some kind of system logs that I can view that will give me more information about what might be happening? Any other methods I can use to troubleshoot this?
