Latest linux git oops with Intel HD Audio ...

CONFIG_SND_HDA_INTEL=y
CONFIG_SND_HDA_CODEC_ANALOG=y
CONFIG_SND_HDA_GENERIC=y


I bisect down to this ...
bb798169d1bb860b07192cf9c75937fadc8610b4 is first bad commit

Simply copying older hda folder (from last week) makes it works again.

Oops from dmesg ...
