https://bugs.freedesktop.org/show_bug.cgi?id=111481 --- Comment #82 from Jaap Buurman --- Running the 5.3.5 Kernel, 19.2.0 Mesa and latest firmware in Arch's repository I am also running into the same issue: [46623.025576] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma1 timeout, signaled seq=75019, emitted seq=75022 [46623.025668] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process chromium pid 24183 thread chromium:cs0 pid 24244 This happened while switching tabs in Chromium. The umr command is not available for me, and AFAIK the official arch repository doesn't have any packages that provide it. -- You are receiving this mail because: You are the assignee for the bug.
