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

If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

I was having problems with i810_audio clocking as well. It turned out to be
the Intel Speedstep support, of all things. *IF* your kernel includes:
CONFIG_X86_SPEEDSTEP_ICH=y
it was possible to end up with a broken value for loops_per_jiffie. I've
attached a patch that fixes the bug and does a few cleanups...
If you don't have the SpeedStep support in your kernel, then your
problem is elsewhere... Good luck... ;)

perhaps a known problem.
a workaround is to turn on the framepointer.
