The snd_atiixp module in the 2.6.8-rc2 kernel doesn't work on my
Compaq Presario R3000 (R3057EA) computer. When I load the module,
the kernel reports:
ACPI: PCI interrupt 0000:00:14.5[B] -> GSI 5 (level, low) -> IRQ 5
ATI IXP AC97 controller: probe of 0000:00:14.5 failed with error -13
The reason it fails is that snd_ac97_mixer() fails for the second
codec (ie when i==1). The patch below makes my sound card work, but
that patch was just based on wild guesses and is probably not
correct.
lspci reports:
00:14.5 Multimedia audio controller: ATI Technologies Inc IXP150 AC'97 Audio Controller
Subsystem: Hewlett-Packard Company: Unknown device 006b
Flags: bus master, 66Mhz, slow devsel, latency 64, IRQ 5
Memory at e8003000 (32-bit, non-prefetchable)
Any idea how to fix this the right way?

I see that this problem has already been fixed in the ALSA CVS, so
sorry for the noise, and thanks for the fix.

It still needs to be fixed in the kernel itself. This bug and the fix
were both reported during the 2.6.6 cycle: we're now in 2.6.8-rc2...
Why the delay on such a trivial bug?

It has been already in mm tree for long time...

...and has been available on the ALSA CVS site, yadda, yadda...
That does nothing to change the fact that the *mainline* kernel tree has
been stuck with a trivial but irritating bug.

The patchset has been ready (that's what Andres includes) since ages,
just not taken by Linus.
