Hello everyone,

In case I am sending this to a list, please CC to me regarding anything
related to this issue. I am not a member of the list.

I am having a Kernel OOPS with 2.6.0-test1-ac2 (same thing under non-
ac2) using ALSA with OSS compatibily enabled on an Intel 82801CA/CAM
AC'97 (ICH3 mobile) integrated Audio.

I have activated "Intel i8x0/MX440, SiS 7012; Ali 5455; NForce Audio;
AMD768/8111" ALSA support and both OSS mixer and PCM compatibility. I
am attaching the oops.log and the ksymoops.log (not sure if the ksym
thing is fine, new to this stuff) The non-compatibility mode seems to
work fine though.

(ALSA driver kernel output bellow)

ALSA device list:
   #0: Intel 82801CA-ICH3 at 0x1c00, irq 10

Also, the OSS (non-ALSA) Intel ICH (i8xx) loads correctly but the sound
output is slow (rate or clocking problem?). My sound was fine under
2.4.21.

(OSS driver kernel output bellow)
i810_audio: Defaulting to base 2 channel mode.
i810_audio: Resetting connection 0
ac97_codec: AC97 Audio codec, id: 0x8384:0x7600 (SigmaTel STAC????)
i810_audio: only 48Khz playback available.
i810_audio: AC'97 codec 0 Unable to map surround DAC's (or DAC's not
present), t
otal channels = 2
i810_audio: setting clocking to 64937

I realy hope you can fix this in the next release and before -test is
over. Please keep me informed of any patches and dont hesitate to ask
if I can help.

Simon
