dmesg with drm.debug=1
The computer running Ubuntu is being used as HTPC connected via HDMI to a
screen projector.
After upgrading to 16.04, it's unusable under production kernel.
The screen starts flickering after a while (it's easily triggered by fast
scrolling e.g. terminal's window). The whole screen get's filled with a noise,
and then the projector gets disconnected for a while. The computer runs fine
on an older kernel (4.2.0-35), it's still
broken on the mainline kernel 4.7.0.
Linux version 4.7.0-040700-generic (kernel@tangerine) (gcc version 5.4.0
20160609 (Ubuntu 5.4.0-6ubuntu1) ) #201608011546 SMP Mon Aug 1 19:48:41 UTC
2016
