Comment # 1 on bug 1225217 from Takashi Iwai

You can try the old kernels from my OBS repo, e.g. home:tiwai:kernel:6.1
  http://download.opensuse.org/repositories/home:/tiwai:/kernel:/6.1/standard/

Could you confirm whether it starts breaking since 6.2.x and 6.1.x works with
the very same intel ucode?

Also, please give the hwinfo output.
