Hi, Takashi:
The reporter rechecked. The real reason is that he replaced the pci/hda instead of the alsa-kernel/pci/hda/patch_realtek.c. After he corrected this, the patch worked well. Thank you very much!
Here is the patch for his machine:

Hi,
I meet with a weird issue. Please refer to the bug 0003674 on bugtrack.alsa-project.org.
It use alc889 codec but the codec vendor id is 0885.
With the alsa-driver-hg20080110.tar.bz2, it works well with option "model=6stack-dig".
But after I simply added the this line into the alc882_cfg_tbl[]: SND_PCI_QUIRK(0x1458, 0xa002, "Gigabyte P35-DS3R", ALC882_6ST_DIG),
The dmesg still show "hda_codec: Unknown model for ALC882, trying auto-probe from BIOS...". and driver will crash.
With this patch, even loading it with option "model=6stack-dig" doesn't help, driver will still crash.
I found a line in the dmesg: "hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0xbe0f0009." The Cad is 0xb.
Very weird.
The codec_mask can change from 0x4 to 0x1: alsa-kernel/pci/hda/hda_intel.c:732: codec_mask = 0x4 alsa-kernel/pci/hda/hda_intel.c:732: codec_mask = 0x1
This implies the hardware is somehow unstable.
Anyway, try the patch below. It cleans up a bit and avoids possible invalid commands, plus puts stack traces at a fatal communication error.
Takashi
