In my opinion, calling panic() on a pre-timeout is not useful, because 
that's really just a normal timeout.  If there were a way to "warn" user 
space that a timeout is about to occur, without a panic or reset, then 
that might be useful.  But as far as I can see, all you're doing is 
redefining the word "timeout".
