Hi Ariff and -current,

Some time after March 15, snd_hda started failing to attach to
pcm0 on my laptop. I haven't managed to nail the change down to
a single commit yet, but I've attached the files:

dmesg.boot-15 boot -v output of March 15 kernel
dmesg.boot-25 boot -v output of March 25 kernel
devinfo-15 devinfo -v output of March 15 kernel
devinfo-25 devinfo -v output of March 25 kernel

There seems to be at least one more message in dmesg.boot-25 which
seems relevant to snd_hda failing to attach:

pcm0: [MPSAFE]
pcm0: [ITHREAD]
+pcm0: hdac_get_capabilities: Invalid rirb size (0)
+device_attach: pcm0 attach returned 6
pcib1: <ACPI PCI-PCI bridge> irq 17 at device 28.0 on pci0

If you need anything more to troubleshoot this, let me know :)

Try reverting hdac.c, down to cvs revision 1.27

No luck with that version and a -DNO_CLEAN build. I'll try a full
kernel and modules recompile next.

Does this has anything to do with recent nexus changes? It seems that
snd_ich plagued by a quite simmilar issue, lately.

Maybe. I'm not sure if it's related. Any pointer to changes which I
can try is much appreciated :)
