Comment # 16 on bug 1156928 from Takashi Iwai

Just to make sure whether we're on the same page: Caleb, could you test the
kernel in OBS home:tiwai:bsc1156928 repo and confirm that the problem still
persists?

It has a backport of the upstream fix 4bdc42094d9c4af75f90ee49b9009ea8dfe41444,
and this should fix the spurious kernel WARNINGs, but it doesn't fix the actual
problem, as it seems.
