I ran into this problem, like someone else on the mailing list.
Pentium III 800MHz 512MB ram
CM8738 sound card
on 2.6.12-rc5-mm1 on gentoo-linux
play sound through alsa, then quit program. I get an oops:
Unable to handle kernel NULL pointer dereference at virtual address 000000a4
printing eip:

*pde = 00000000

I reported it here:
http://bugzilla.kernel.org/show_bug.cgi?id=4662
thinking it would appear on lkml, but it didn't. Anyway, tell me if more
info is needed.
Thanks in advance.
