>Environment:
System: NetBSD shog.sudog.com 3.99.20 NetBSD 3.99.20 (GENERIC.MPACPI) #0: Sat May 20 19:16:43 PDT 2006 root@khan.sudog.com:/v/netbsd/src/sys/arch/i386/compile/GENERIC.MPACPI i386
Architecture: i386
Machine: i386
(Currently running i386 because that *does* work.)
>Description:
	Intel D945GNTL motherboards with built-in video based on 
	"Intel® GMA 950 onboard graphics subsystem" with or without a
	PCI nVidia TNT2-64 video card installed generates (from memory!)

	cnopen: no console device
	panic: error no /dev/console
>How-To-Repeat:
	Build your own amd64 installer, or build your own netbsd-3.0_STABLE
	or download the boot1.fs/boot2.fs from:
	/pub/NetBSD-daily/netbsd-3/200607240000Z/amd64/installation/floppy
	... and then try to boot on the following machine:
	Intel Pentium D 930 (dual core, EM64T)
	Intel D945GNTL Motherboard with Intel GMA 950 gfx onboard
	1 GB RAM

	Think onboard video is the problem after reading mailing list notes
	regarding cnopen() failing after iterating incorrectly through
	multiple vga devices, and install nVidia TNT2-64 PCI board hanging
	around into it. Watch it all fail all over again.
>Fix:
	Getting the machine running NetBSD requires plain i386 install disks,
	which work (almost) perfectly, except for a dmesg with lots of ^M in
	it.
