Hello,

I am experiencing freezes with kernel 5.3.2 and amdgpu on a Vega 64 card.

This happens during games (I experience it on CS:GO) but it is a bit random and
takes time to eventually trigger.
Once it triggers my dmesg is filled with errors:


[ 9156.537524] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize
parser -125!
[ 9156.747176] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize
parser -125!
[ 9156.747224] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize
parser -125!
[ 9156.883220] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize
parser -125!
[ 9156.883285] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize
parser -125!

When it happens, the image hangs and PC is unresponsive. Sometimes I manage to
switch to a TTY, but then the screen is corrupted.

HW:
- AMD Ryzen 2700X CPU
- AMD RX vega 64

SW:
- Kernel 5.3.2
- Mesa 19.2.0
