regression in handling VIA onboard sound chip, ALSA, 2.6.13, 2.6.14-rc4

[René Rebe]

Hi all,

up to 2.6.12-* the VIA onboard sound chip did always work as expected. 
Recently (2.6.13.* - I also tested 2.6.14-rc4) I get a timeout reading 
AC97 registers:

PCI: Via IRQ fixup for 0000:00:11.5, from 0 to 4
via82cxxx: Six channel audio available
PCI: Setting latency timer of device 0000:00:11.5 to 64
via82cxxx: timeout while reading AC97 codec (0xAA0000)
ac97_codec: AC97 Audio codec, id: ADS112 (Analog Devices AD1981)
via82cxxx: board #1 at 0xE000, IRQ 20

And no entry in /proc/asound/cards, there is only one for the Midiman Delta 
1010 also in the system:

0 [M1010          ]: ICE1712 - M Audio Delta 1010
                     M Audio Delta 1010 at 0xb400, irq 19

An the working kernel (2.6.12.5) I get this in dmesg:

PCI: Via IRQ fixup for 0000:00:11.5, from 0 to 6
PCI: Setting latency timer of device 0000:00:11.5 to 64
codec_read: codec 0 is not valid [0xfe0000]
codec_read: codec 0 is not valid [0xfe0000]
codec_read: codec 0 is not valid [0xfe0000]
codec_read: codec 0 is not valid [0xfe0000]

However the device works well, devices entry:

0 [M1010          ]: ICE1712 - M Audio Delta 1010
                     M Audio Delta 1010 at 0xb400, irq 18
1 [V8235          ]: VIA8233 - VIA 8235
                     VIA 8235 with AD1980 at 0xe000, irq 22

Any known regressions or something I could give a try?

Yours,

No wonder, they are messages from OSS via82cxxx driver...

You are so right - sorry for the stray report. With the ALSA driver all is 
fine as usual.
