Regression: audio not detected "cannot build controls"

Sound on my Sony Vaio used to work back in 2.6.36 but no longer works.
At boot time I see a message like this:

[ 7.159241] hda_codec: ALC889: BIOS auto-probing.
[ 7.159246] hda_codec: ALC889: SKU not ready 0x411111f0
[ 7.160629] input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input6
[ 7.164300] hda_codec: cannot build controls for #0 (error -16)
...
[ 7.215622] input: HDA Intel Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input7
[ 7.216004] HDA Intel 0000:01:00.1: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[ 7.216007] hda_intel: Disable MSI for Nvidia chipset
[ 7.216094] HDA Intel 0000:01:00.1: setting latency timer to 64
...
[ 13.780090] hda-intel: IRQ timing workaround is activated for card #1. Suggest a bigger bdl_pos_adj.

and I don't see the sound device in my Pulseaudio configuration so of
course I don't get anything out of the speakers.

I haven't tried to bisect this yet, presumably this bug came in along
with the main ALSA changes for this cycle. Hope it's a known issue
with a fix somewhere already?

Thanks,
