            Bug ID: 109085
           Summary: Radeon driver crashes with a message "ring 0 stalled
                    for more than 10344msec" when using Citra and others
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium

dmesg output

Overview: 

Radeon driver crashes and completely corrupts the screen during an attempt to
use Citra emulator (always right after loading a game), and sometimes randomly
during other GPU-demanding tasks, like using hardware video decoding through
VDPAU. Strangely, the X server itself doesn't crash, and i can still see and
move the mouse cursor, although heavily corrupted.

Attached dmesg from the time of the crash.


Steps to Reproduce: 

Open Citra, try to load any game.


Actual Results: The driver crashes, resulting in screen corruption.

Expected Results: Citra running the game or failing safely without crashing the
driver.

Software versions:

Linux 4.19.9
Mesa 18.3.1
Xorg 1.20.3
xf86-video-ati 18.1.0
