Comment # 1 on bug 987950 from Takashi Iwai

Strictly speaking, it's no "crash" but just a kernel warning.  But it's
annoying, indeed.

Is this a kernel regression?  If yes, which kernel did it start showing it?
And, does this problem exist when you use TW kernel (from OBS Kernel:stable
repo)?

In anyway, please give hwinfo output and the full output of dmesg after a fresh
boot.
