Ubuntu – HOW TO FIX drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout ? ON MY RYZEN 5 2400G APU


My PC freezes randomly without any workload. only ALTSyS REISUB works. I installed fresh ubuntu 18.04.2 on my system and this is the only OS installed in my pc. I dont have any other Graphics Card And It only uses the GPU integrated with the Ryzen5 2400G APU.
In the log I find this:

14:13:28 kernel: **[drm:amdgpu_job_timedout [amdgpu]] *ERROR*** ring gfx timeout, last signaled seq=8349, last emitted seq=8351

What is "ACPI BIOS Error (bug)"?, and what is amdgpu_job_timedout [amdgpu]] ERROR ring gfx timeout**
How can I solve the problem?
