Weird drm:hsw error (no idea where it is coming from)

Asked by Michael Heuberger

In my dmesg I see this:

[ 366.976144] [drm:hsw_unclaimed_reg_clear] *ERROR* Unknown unclaimed register before writing to c7204
[ 366.976145] [drm:hsw_unclaimed_reg_check] *ERROR* Unclaimed write to c7204

No idea where this is coming from and to what package this error belongs to.

Thanks for helping!
Michael

[68137.084209] [drm:hsw_unclaimed_reg_check] *ERROR* Unclaimed write to 70088

screen gets dark, but after a few seconds it's back again.
