I am running on arch linux: Linux arch 5.2.13-arch1-1-ARCH #1 SMP PREEMPT Fri Sep 6 17:52:33 UTC 2019 x86_64 GNU/Linux I am running wayland via sway. My gpu is a Radeon RX Vega 64. While in my sway session the image on my screen froze but audio from a video continued to play. I was able to ssh in from a different machine and found this message with dmesg: BUG: kernel NULL pointer dereference, address: 0000000000000360 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 0 P4D 0 Oops: 0002 [#1] PREEMPT SMP PTI CPU: 1 PID: 12766 Comm: kworker/u16:0 Not tainted 5.2.11-arch1-1-ARCH #1 Hardware name: ASUS All Series/Z87-PLUS, BIOS 2103 08/15/2014 Workqueue: events_unbound commit_work [drm_kms_helper] RIP: 0010:dc_stream_retain+0x5/0x20 [amdgpu] <Code and registers omitted.

Not even `sudo reboot` completed despite killing the ssh session. I had to hard reset the machine. Potentially related is that since roughly a week I have been experiencing intermittent screen freezes from time to time that would resolve themselves after about 10 seconds with a message like this in dmesg: drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:47:crtc-0] flip_done timed out [drm:amdgpu_dm_atomic_check [amdgpu]] *ERROR* [CRTC:47:crtc-0] hw_done or flip_done timed out
