Public bug reported: Since upgrading to 20.04 from 19.10 I can reliably hang my system by loading Google Maps in Chrome and zooming in and out.
After turning on DRM debugging: echo 0x1ff | sudo tee /sys/module/drm/parameters/debug I can see the following message in the kernel log: [16333.092468] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx_0.0.0 timeout, signaled seq=2542114, emitted seq=2542116 [16333.092537] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process pid 0 thread pid 0 [16333.092540] [drm] GPU recovery disabled. It seems to be this upstream bug: https://gitlab.freedesktop.org/drm/amd/issues/892 I have two workarounds: * Running Chrome with AMD_DEBUG=nongg fixes the issue on 5.4.0-26 * With the latest upstream kernel, 5.6.7-050607, Chrome can load google maps with no issues.
