I guess it's a problem with 2.6.17 kernel. Maybe the wrapper for the
new kernel API in alsa-driver tree is somehow broken. Check compiler
warnings especially for the compilation of hda_codec.c, too.
I didn't get oops, at least. Tthere was another bug that got fixed
today, so please update to the latest version from
hg.alsa-project.org (not from hg-mirror).
