            Bug ID: 102765
           Summary: HP Spectre x360 internal monitor intermittently
                    flickering & freezing
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)

dmesg output with drm.debug=0xe set in the boot options

This is a follow-up to BZ#101380, where I'm getting similar screen flickering,
freezing, and whiting out symptoms to those described there, but it had
previously been closed for lack of the requested debugging information. (If
they'd be of value, I have some additional videos of the misbehaviour that I
could upload, but the video already linked from that bug gives a pretty decent
example of the visible symptoms.

The attached dmesg log was generated with drm.debug=0xe in the boot options,
just after the internal monitoring had gone through an episode of freezing and
whiting out (and while it was still flickering a bit).

The most suspicious looking lines are these ones:
