Comment # 9 on bug 1221504 from Takashi Iwai

Thanks.  Do you happen to still have *-150 kernel?  If not, I'm building a
package from the same code in OBS home:tiwai:bsc1221504 repo.
Once after the build finishes (takes an hour or so), it'll be available at
  http://download.opensuse.org/repositories/home:/tiwai:/bsc1221504/pool/

Please verify with this kernel (or the existing *-150 kernel) whether the
problem is seen there or not.  If the problem is gone, it means that the bug
was re-introduced by some other changes since that version.
