Trying again to get this message to the alsa-devel list, as recommended
by the Debian maintainer of the kernel, without being subscribed. Does
alsa not have a bug report page?

Booting kernel 2.6.38  hangs at:
During boot of kernel 2.6.38 (and 2.6.37) udev bugs out:
Waiting for /dev to be fully populated
BUG: Unable to handle kernel paging request at ffffc90013cd8000
axz_probe+ ... [snd_hda_intel]
...lots of output lost...
udevadm timeout 180 sec ...
udevd[390]: worker [439] failed while handling

No sound card is recognized after the timeout of the boot as shown above.
According to the /proc/asound/cards there are no sound cards

See bug Debian bug #619034 for more information.

This problem was also reported as Debian bug #613979, as kernel ticket


and sent to this mailing list in February 2011.

snd_hda_intel works properly with 2.6.32-5-amd64 (and earlier kernels).
