>Release:        2.9
>Environment:
	
	System      : OpenBSD 2.9
	Architecture: OpenBSD.i386
	Machine     : i386
>Description:
	When booting with the GENERIC kernel, the boot process
	hangs at the following point:

	pccom0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo
	fdc0 at isa0 port 0x3f0/6 irq 6 drq 2
	fd0 at fdc0 drive 0: 1.44MB 80 cyl, 2 head, 18 sec
	biomask c848 netmask c868 ttymask d8ea
	pctr: 686-class user-level performance counters enabled
	mtrr: Pentium Pro MTRR support
	dkcsum: wd0 matched BIOS disk 81

	I have seen this problem on  two different machines,
	one running 2.8 and 2.9, the other just 2.9.

>How-To-Repeat:
	repeat the boot process
>Fix:
	1. Boot with the -c flag and then disable pcibios.
	2. Use the config -e /bsd -o /bsd.nopcibios etc..
           command to permanently disable pcibios
