Hi folks,

i am new to bugreporting, but due to having a new system and this bug, i want
to contribute something to this situation.

I have almost the same behavior as stated in comment 1.

My Xorg freezes every session no matter what i do. I could only get the last
dmesg befor i had to hard reboot over ssh, cause this was the only thing
working.

2 Examples:
[ 1184.577790] [drm:amdgpu_dm_commit_planes.constprop.0 [amdgpu]] *ERROR*
Waiting for fences timed out or interrupted!
[ 1189.697729] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout,
signaled seq=53043, emitted seq=53045
[ 1189.697797] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information:
process Xorg pid 1398 thread Xorg:cs0 pid 1409
[ 1189.697799] [drm] GPU recovery disabled.


[ 708.286318] [drm:amdgpu_dm_commit_planes.constprop.0 [amdgpu]] *ERROR*
Waiting for fences timed out or interrupted!
[ 713.406528] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout,
signaled seq=104848, emitted seq=104850
[ 713.406594] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information:
process Xorg pid 1402 thread Xorg:cs0 pid 1414
[ 713.406596] [drm] GPU recovery disabled.


I have already set AMD_DEBUG=nodam in /etc/environment and in ~/.profile.
Last time i played World of Tanks via Wine and DXVK the same freeze occured,
again the same error that xorg pid timed out...

It is happenening after 1 Minute logged in or 1 hour.

My System specs are:
R7 3700x
Powercolor R5700XT Red Dragon Silent Bios enabled
Gigabyte X570 I Aourus Pro WIFI
UBUNTU 18.04.3 LTS with Kernel 5.3.8 and Padoka unstable PPA (Mesa 19.3)

I have no NVME SSD and i have no Monitoring applications running.

Tests done:

-With Kernel 4.15 standrad Ubuntu Kernel and AMDGPU-PRO installed, everything
runs fine without a freeze.
- With Kernel 4.18 and Mesa 19.0.8 no freezes occured, kernel does not
recognize rx5700, so no amdgpu modul is loaded.

freezes occured with kernel 5.3.7 and 5.3.8 and in combination with padoka and
oibaf ppa (Mesa 19.3).

If i can help with further information pls guide me to dig in my system the
infos u need.
