Ok, what happens here is that the $PIR code ends up using IRQ 14 for a=20 virgin-routed link. You can just use a tunable to override this like so: hw.pci.link.0x1.irq=3D12 That should make the vga adapter use irq 12 rather than irq 14. If you hav= e a=20 BIOS setting that says 'enable VGA irq' you could also try turning that on.= =20 However, you'd probably much rather be running with ACPI + APIC enabled=20 anyway. =2D-=20 John Baldwin <jhb@FreeBSD.org> =A0<>< =A0http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =A0=3D =A0http://www.FreeBSD.org
