https://bugs.freedesktop.org/show_bug.cgi?id=111481 --- Comment #154 from L.S.S. --- I'm not sure about how to locally pipe dmesg log to file so the moment when the system freezes could be captured. And interestingly, the GCVM_L2_PROTECTION_FAULT errors that I saw from journalctl when it froze last time went missing somehow... maybe I mistook it, but whenever the system froze the following lines are guaranteed to show up (ring sdma0 timeout), so it's most likely sdma0 type. [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout, signaled seq=151787, emitted seq=151789 [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process Xorg pid 1838 thread Xorg:cs0 pid 1862 Currently the system is running okay as I haven't opened Nemo yet (which can almost 100% cause the freeze). Web browsers such as Firefox and Chrome currently don't cause the freeze. -- You are receiving this mail because: You are the assignee for the bug.
