>Release:        FreeBSD 2.2-960323-SNAP i386
>Environment:

	ASUS P/I-P55T2P4 Triton II motherboard w/ AHA-2940 and 2 unused
	Quantum Fireball 1280MB Hard Drives

>Description:

	boot floppy panics in sysinstall when there are two unused Quantum
	Fireball 1280MB Hard Drives.  Works okay with just one drive or if one
	or both have been fdisked.
	Many pages of panic messages.  Here is the last page:
	panic: unknown/reserved trap

	Fatal trap 12: page fault while in kernel mode
	fault virtual address	= 0xc
	fault code		= supervisor write, page not present
	instruction pointer	= 0x8:0xf01a12b1
	code segment		= base 0x0, limit 0xfffff, type 0x1b
				= DPL 0, pres 1, def 32 1, gran 1
	processor eflags	= interrupt enabled, resume, IOPL=0
	current process		= 1 (sysinstall)
	interrupt mask		=
	panic: page fault
	panic: unknown

	Fatal trap 1: privileged instruction fault while in kernel mode
	instruction pointer	= 0x8:0xf01da862
	code segment		= base 0x0, limit 0xfffff, type 0x1b
				= DPL 0, pres 1, def 32, gran 1
	processor eflags	= interrupt enabled, resume, IOPL=0
	current process		= 1 (sysinstall)
	interrupt mask		=
	panic: privileged instruction fault
	panic: unknown/reserved trap

>How-To-Repeat:

	boot the 960323-SNAP boot floppy with ASUS triton 2, 2940, and two
	new unused Quantum Fireball 1280's

>Fix:
	
	workaround is to boot with one drive, partition it, and reboot with
	both drives.
