Does this patch fix the issue? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/ ?id=202ead5a3c589b0594a75cb99f080174f6851fed
Kernel 5.13.13 has this patch already. So apparently it does not fix the problem. It occurs with radv, amdvlk, and amdvlk-pro. External monitor is attached via HDMI (although it happens without ext. monitor too).
Sometimes dmesg does not contain above mentioned lines but dGPU is still unusable. Sometimes DXVK delivers VK_ERROR_DEVICE_LOST status even during runtime.
