I've had this problem for a while, over several releases. Keyboard will freeze up (key presses do nothing). Mouse pointer can be moved but clicks do nothing. Only solution was to reboot using the power button, which does trigger a clean shutdown.
I've been chalking it up to some kind of hardware issue. Nothing is ever logged. But today it happened again, and I found these messages in /var/log/messages just before the reboot: Apr 14 18:17:50 fabrik /bsd: [drm] *ERROR* ring sdma1 timeout, signaled seq=10792, emitted seq=10792 Apr 14 18:17:50 fabrik /bsd: [drm] *ERROR* Process information: process pid 0 thread pid 0 Apr 14 18:17:50 fabrik /bsd: amdgpu_device_suspend_display_audio: stub dmesg below, happy for any suggestions what this might mean, or is it likely unrelated, or what additional info may be helpful.
