intel8x0 not working in kernels greater than 2.6.9

intel8x0 not working in kernels greater than 2.6.9

[David Gómez]

Hi all ;),

I got alsa working in 2.6.8, but after installing 2.6.9, sound just
vanished :(. Using native alsa or oss emulation makes no difference,
and i've tried all kind of applications (mpg123, ogg123, xine,
alsaplayer...). Logs are full of messages like
this:

codec_read 0: semaphore is not ready for register 0x2c

I've tested 2.6.9 and 2.6.10rc2 with the same bad results. Reverting
to 2.6.8 cause sound  to work again.

TIA,

--

I believe this is a known bug.  Fix was posted to alsa-devel and LKML
earlier this week.

We have asked Linus to put the fix in 2.6.10.

What happens if you compile ALSA 1.0.7 on 2.6.8 kernel?
If it works, the problem is in the kernel core side.
