The already attached dmesg log is from a session with drm.debug=0xe, and runs
all the way from boot to an internal screen freeze+flicker+recovery.
Unfortunately, the only errors listed are the ACPI ones from early in the boot
cycle (and the response for the ACPI devs was that they don't see how those
could be related to problems with the internal monitor).

This is a video of what the freezing misbehaviour looks like on my machine:

Bug #101380 was a previous report of a similar issue, and their video is what
made me believe they were encountering the same problem:
