	FreeBSD 2.1-stable as of about May 27th, 1996.

>Description:

	I woke up this morning to find a kernel dump in /var/crash.  
	I'll keep it around for a little while, but not forever. 
	If someone wants to analyze it, let me know.  If not, tell
	me it's junk and I'll delete it.

	idiom# gdb -k kernel.5 vmcore.5
