dmesg output

I have an RX 480. Every few hours after kernel 5.4 (!) I've been getting random
GPU hangs, and after kernel 5.9, they became not only more frequent, but
afterwards the kernel sent messages like 

Nov 29 15:44:31 reimu kernel: [drm] Bailing on TDR for s_job:34a, as another
already in progress
Nov 29 15:44:31 reimu kernel: BUG: kernel NULL pointer dereference, address:
0000000000000020
Nov 29 15:44:31 reimu kernel: #PF: supervisor write access in kernel mode
Nov 29 15:44:31 reimu kernel: #PF: error_code(0x0002) - not-present page

And an Oops right afterwards
Oops: 0002 [#2] PREEMPT SMP NOPTI

The full dmesg is attached. Kernel is compiled with Archlinux kernel
preferences, but using a kernel directly from kernel.org and compiled with the
modules I need give me the same error.

Attached error.
