I believe I tried just reverting
9c99e5e51988798af2a687ef9b1716dd79388550 before, but that did not
help.

I guess I'll try with these reverted, next:

pavel@amd:/data/l/linux-n900$ git show
9c99e5e51988798af2a687ef9b1716dd79388550 | git apply -R

62aa292b3eae920a80c2fd0ed0601a70328627f6 | git apply -R
pavel@amd:/data/l/linux-n900$

...seems to be broken already. I guess its time to
bisect... hmm. Tried bisecting, but soundcard does not work
there. Will do it manually...

Best regards,
