Crap. This is one of those crashes where the sound people, the PCI people,
the ACPI people and the PM people all earnestly hope that it's the other
guy's bug and you and I are left with a mess on our hands.

Possibly the card didn't get powered up. I know there's a way to get all
those snd_printk()'s to print something, but I never have much success
finding the right value for the right /proc file to make it happen.

So can you add this please?

and let us know what it says?

Also, it would be useful if you could disable the sound driver in config
and see if you can get it booted. If so, then generate the `dmesg -s
1000000' output for good and bad kernels and let's see what they look like.
Thanks.
