Summary:                    regression in snd-cs4281 in recent 2.6.16-rcX
kernels
Description: 
In the recent 2.6.16-rc kernels snd-cs4281 broke for me.
(I think since 2.6.16-rc2, but Im not sure atm. In 2.6.15 the card works
fine.)

# > modprobe snd-cs4281
ACPI: PCI Interrupt 0000:00:08.0[A] -> Link [LNKC] -> GSI 5 (level, low)
-> IRQ 5
never read ISV3 and ISV4 from AC'97
ACPI: PCI interrupt for device 0000:00:08.0 disabled
CS4281: probe of 0000:00:08.0 failed with error -5

and no soundcard is found.

If you need more info or want me to test something, please say so.


kind regards,
Jens

same problem on a debian sid, IBM Thinkpad X20.

The switch from 2.6.15 to 2.6.16 broke the sound

Also happens here.
Debian unstable, custom-compiled kernel, as well as the precompiled kernel
in the Debian repository don't work.

dmesg on a kernel, compiled with support for ACPI:
ACPI: PCI Interrupt 0000:00:08.0[A] -> Link [LNKC] -> GSI 5 (level, low)
-> IRQ 5
ALSA sound/pci/cs4281.c:1577: never read ISV3 and ISV4 from AC'97
ACPI: PCI interrupt for device 0000:00:08.0 disabled
CS4281: probe of 0000:00:08.0 failed with error -5

dmesg on a kernel, compiled without support for ACPI:
PCI: Found IRQ 5 for device 0000:00:08.0
ALSA sound/pci/cs4281.c:1577: never read ISV3 and ISV4 from AC'97
CS4281: probe of 0000:00:08.0 failed with error -5

It doesn't seem like ACPI is the problem. The second kernel was compiled
with no support whatsoever for power management. If you need me to try
some specific configuration, do say so.
