Description hroi 2001-03-13 00:00:01 UTC

kernel hangs when loading snd:

# kldload snd
ppc0: parallel port not found
pcm0: <Creative EMU10K1> port 0xcc00-0xcc1f irq 15 at device 9.0 on pci0
(machine hangs)

I do not know what is up with ppc0. parport has been disabled in bios.
Enabling options DDB, INVARIANTS, INVARIANT_SUPPORT and DIAGNOSTIC in kernel gives only this much extra:

# kldload snd
ppc0: parallel port not found
Vendor specific Word = ffff
pcm0: <Creative EMU10K1> port 0xcc00-0xcc1f irq 15 at device 9.0 on pci0
(machine hangs)

kernel conf: http://asdf.dk/sjov/BASSPUMP
dmesg:       http://asdf.dk/sjov/dmesg.txt

I don't know how to debug this, there is no panic. The card is known to work in win2k on the same machine.

How-To-Repeat: 
# kldload snd

Is this still a problem with more recent sources?

Update: It works!

Fiddling with the BIOS, forcing it to assign IRQ's and DMA's to PCI
devices only, seems to fix the problem. I can now play sound in FreeBSD.
