A strange problem has started to occur recently on my machine. It seems
to enjoy rebooting for no reason whatsoever. No messages are usually
left. Occasionally, the message 

	Panic: kmem_map too small...
	Updating disks before rebooting.

Appears. Sometimes I get a vm_fault() error message (but rarely).

Anyone any ideas where I should even start looking???

Config is below for those interested.
