Already tried out some different things: - Tried the latest linux kernel - Fiddled with amdgpu & radeon kernel module options - Tried running the amdgpu kernel module instead of radeon
Had to SSH into the machine to do anything (usually the system locks up). Some error messages from the fiddling: # kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=19833, emitted seq=19835 # kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process Xorg pid 1758 thread Xorg:cs0 pid 1798 # kernel: [drm] Fence fallback timer expired on ring sdma1 # kernel: [drm] Fence fallback timer expired on ring gfx -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1975566 Title: radeon / amdgpu bad performance or panics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1975566/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
