While watching a video using mpv (default config) the system will hang eventually - this is actually a kernel oops that happens after lots of GPU resets every second or so (in the span of ~5 minutes; it seems to be alright in the beginning):

Aug 12 00:46:49 mashedpotato kernel: [drm] UVD and UVD ENC initialized successfully. Aug 12 00:46:49 mashedpotato kernel: [drm] VCE initialized successfully. Aug 12 00:46:56 mashedpotato kernel: amdgpu 0000:01:00.0: GPU pci config reset Aug 12 00:46:59 mashedpotato kernel: [drm] PCIE GART of 256M enabled (table at 0x000000F400000000).

This block of warnings repeats itself many times and then it is this error:

Aug 12 00:52:20 mashedpotato kernel: amdgpu 0000:01:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring sdma0 test failed (-110) Aug 12 00:52:20 mashedpotato kernel: [drm:amdgpu_device_resume [amdgpu]] *ERROR* resume of IP block <sdma_v3_0> failed -110 Aug 12 00:52:20 mashedpotato kernel: [drm:amdgpu_device_resume [amdgpu]] *ERROR* amdgpu_device_ip_resume failed (-110). Aug 12 00:52:25 mashedpotato kernel: BUG: kernel NULL pointer dereference, address: 0000000000000000 Aug 12 00:52:25 mashedpotato kernel: #PF: supervisor instruction fetch in kernel mode Aug 12 00:52:25 mashedpotato kernel: #PF: error_code(0x0010) - not-present page

In the end it is a kernel oops, log is in the attachment. The system is only recoverable via a hard reset afterwards, though the sound from a video keeps playing just fine.

My system is a ASUS laptop, TUF FX505-DY with the latest BIOS. lspci:

I have amdgpu.gpu_reset=1 in my kernel commandline as I want to figure out another issue - sometimes the system hangs after locking and disabling screen, and I guess it is GPU reset-related.
