It does not seems to affect normal behaviour, but maybe the report could be
interesting for maintainers.
Sorry if this has already been reported; if more information is needed just
let me know (please CC: me as I'm not subscribed to lists.)
Many thanks.

Which drm driver are you using? I didn't spot anything in your module list
but might have missed it. Booting with drm.debug=0xe and grabbing dmesg
will tell us for sure.

Attached the drm.debug output, grepped for "drm". Let me know if I stripped
something useful.
