atiixp ac97 timeout gives error (2.6.7-rc2)
PATCH 1/1 atiixp ac97 timeout gives error (2.6.7-rc2)
Hi,
I found that with 2.6.7-rc2 alsa refuses to recognize my atiixp as a working sound card.
My atiixp is of a compaq nx9110 notebook.
pci stuff:
0000:00:14.5 Class 0401: 1002:4341
Subsystem: 103c:006b
Flags: bus master, 66MHz, slow devsel, latency 64, IRQ 5
Memory at d0003000 (32-bit, non-prefetchable)or:
0000:00:14.5 Multimedia audio controller: ATI Technologies Inc SoundMAX Integrated Digital Audio
I've patched the atiixp driver by ignoring the error when the driver loads. If I recall correctly, this was the normal behaviour in 2.6.5: a timeout warning was issued, but the "card" functioned is it should.
If an alsa developer could point me to the "right" way, I can make the patch a real patch.

It's already fixed in the mm tree. Please give a try.

Yes, it works. Thanks. Now I also understand what happens :-).
