--- Comment #7 from Bernd Steinhauser linux@bernd-steinhauser.de --- Created attachment 125333 --> https://bugs.freedesktop.org/attachment.cgi?id=125333&action=edit dmesg output
dmesg output from the currently running system.
Attaching this as I noticed that I do get those vblank/flip messages even now, when I didn't experience the bug (yet).
