Description Joe Talbott 2004-06-14 20:50:25 UTC
	Kernel trap 9: general protection fault while in kernel mode
	when booting FreeBSD 5-CURRENT (snapshot 20040324) amd64 just after
	cdrom drive probe.  This happens every time I boot from this cd 
	(I burned several copies on different machines and checked md5 
	checksum) When booting 5.2.1-RELEASE (amd64) the system hangs at
	this points and keyboard input (Ctrl-Alt-Del) has no effect. I can 
	boot 5.2.1-RELEASE i386, 4.9-RELEASE, and DragonFlyBSD 1.0-CURRENT
	and have done numerous buildworlds as a rudementary test of hardware
	with no problems.  This happens with ACPI disabled as well.

[THIS IS HAND TRANSCRIBED]
