System: NetBSD berkshire.research.att.com 1.5.2_ALPHA NetBSD 1.5.2_ALPHA (BERKSHIRE) #6: Thu Aug 9 09:14:28 BST 2001 smb@berkshire.research.att.com:/usr/src/sys/arch/i386/compile/BERKSHIRE i386


>Description:
	I was trying to get to a Web site.  My browser froze.  The machine
	was still alive, so I logged into it remotely.  X was no longer
	running, but I stil had the X display on my screen.  cntl+alt+f2,
	etc., didn't help.  I suspended via 'zzz' and woke it up; it
	never responded after that, until it rebooted.
	I have the core dump.

	was running.
