   >Description:

	   The machine deadlocks so that
	   - Trying to log in from console allows me to type "root", but after
	   pressing return the tty locks up
	   - Network and NFS still work
	   - Any network connections lock up as soon as they do *any*
	   filesystem (?) I/O.

Possible correction/clarification to this one: It seems that new processes
cannot be started, but file system I/O is possible.  Existing processes
work.

I really miss a "Panic" button here, by any chance could it be implemented
somehow (adding code to pcvt to make some little-used key to panic and
dump, for example).

	   - This happened today three times in row
	   - I has happened before, but not this frequently
It has happened...
	   - There is nothing special on console
	   - It apparently happens on very loaded systems only

This evening it has happended twice.  I replaced Intel plato motherboard
with ASUS to see if that has any effect.
