Freeze before launching android emulator
X become unresponsive occasionally during the day, it usually happens before
launching applications but it's not reproducible constantly, it also happens
while browsing in Firefox. I have attached the log when it happened before
launching the android emulator (amdgpu.vm_debug was set to true to show the
stack trace). I can reboot the machine with a sysRq but everything graphical is
freeze. Sometime it says gfxhub others mmhub.
Ubuntu 18.04, Kernel is 4.17 from the kernel-ppa, asrock ab350m pro4 updated to
the latest test firmware with AGESA 1.0.0.3b to see if it fixed the problem but
still happens, mesa stack from the oibaf ppa, with padoka it seems the error
appears less frequently and the error is usually silent and can only see this
"[drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled
seq=453604"</pre>
