dmesg
I'm using the latest code from amd-staging-4.9 branch of ~agd5f/linux.
The screen locks are happening randomly when playing videos (in browser or =
with
mplayer) or when running commands that output a lot of text in xterm.
When it happens, contents of the screen are no longer refreshed, except for
mouse pointer.
Following errors are reported:
[drm:drm_atomic_helper_commit_cleanup_done] *ERROR* [CRTC:38:crtc-0] flip_d=
one
timed out
[drm:dc_commit_surfaces] *ERROR* dm_dc_surface_commit: acrtc 0, already busy
My reproducer is to fill the screen with two xterm windows next to each oth=
er
and generate random lines of text in both of them, using command like this =
for
example:
tr -dc a-z1-4 </dev/urandom | tr 1-2 ' \n' | awk 'length=3D=3D0 || lengt=
h>50' | tr
3-4 ' ' | sed 's/^ *//' | cat -s | sed 's/ / /g' | fmt
It usually takes just a couple of minutes for the screen lock to happen.
I've bisected the issue to this commit:
