Comment # 3 on bug 1181327 from Takashi Iwai

Thanks.  Yes, it looks like the modesetting being used.

The error reminds me of an old issue with DP-MST, happening with two monitors.

You can try openSUSE-15.2 KOTD in IBS Devel:Kernel:openSUSE-15.2 as lots of DRM
fix patches have been backported recently, although I don't think this bug is
covered by those.

BTW, how is this bug reproducible?  Does it happen always, or only very
occasionally?
