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

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.

Hm, how 2.6.17rc1?  The timeout check in the probe routine was fixed.
