System's journal log with 4.18-rc5
I have a hardware whose MB is Acer Nitro N50-100 (AMD Ryzen:
ZD2600BBM68AF_38/34_Y) and graphic card is AMD Radeon RX 580.
I have tried Linux kernel 4.18-rc5 with parameters "amdgpu.dc_log=1
drm.debug=7" on this hardware. System display will be gone suddenly and not
come back after amdgpu is loaded and gdm is started. However, I still can ssh
into the system. The error was shown:
[ 23.007070] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout,
last signaled seq=173, last emitted seq=175
[ 23.007087] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout,
last signaled seq=26, last emitted seq=27
[ 23.007088] [drm] GPU recovery disabled.
[ 23.007090] [drm] GPU recovery disabled.
The attachment is the full journal log.
If I blacklist amdgpu module, it can boot and go into the desktop environment
correctly.
