Well, how do you define "crash"? :-))

The symptoms I'm talking about are:

For more than 15 minutes:
*) Not responsive to network (no ping, no telnet)
*) Not responsive to console (no VT switching, no
noticeable reaction on keyboard input)
*) No noticeable disk I/O

I have verified this behaviour on two different
machines now (out of two tested)
