DFly 1.4 Intel 83875P no boot

["EvilTwinkie" <eviltwinkie@xxxxxxxxxxxxxxx>]

Greetings,

DFly 1.4
Tyan GS12

Intel 82875P

I cannot boot off the LiveCD, or from an installation dumped on a drive on a
separate system. FreeBSD 4.x + 5.x + 6.x are all OK.

During the boot process it hits the agp0 detection and then sits there like
an idiot. CTRL+ALT+DEL work fine although no ACPI messages appear.

Last three lines appear are:

boot -v

agp0.pci0.pcib0.legacypci0.nexus0.root0
agp0: <Intel 83875P host to AGP bridge> [tentative] mem 0-0x1ffffff at
device 0.0 on pci0
agp0: allocating GATT for aperture of size 128M

What should come next is the USB stuff but instead, nothing.

Single usermode is no joy
ACPI disabled is no joy
Safemode is no joy
AGP module disable via boot prompt no joy

This is my first time messing with DFly and so far I am somewhat concerned
that this bug has not been addressed. How stable is DFly? Ready for
production?

Cheers!
