--- Comment #8 from Anton Repko (anton at a-repko.sk) ---
The same happened with the following setup:

- Kernel 5.8.14 and 5.9 with mostly Gentoo kernel config
- AMD Ryzen 7 PRO 4750G CPU+iGPU
- ASRock A520M-ITX/ac mainboard + ECC UDIMM memory

The trace mentioned above disappeared when I updated BIOS (v. 1.20 from
2020/9/18, it contains AGESA 1.0.8.0). However, I'm still not able to run ROCm
OpenCL (tried various versions, including 3.7 and 3.8), system either hangs, or
(if the program is killed early) dmesg shows

 Evicting PASID 0x8001 queues

BTW, clinfo causes GPU resets, and leaves 99% GPU utilization, while dmesg
shows something like

 qcm fence wait loop timeout expired
 The cp might be in an unrecoverable state due to an unsuccessful queues 
 preemption
 amdgpu: Failed to evict process queues
 amdgpu: Failed to quiesce KFD
 amdgpu 0000:07:00.0: amdgpu: GPU reset begin!
 [drm] free PSP TMP buffer
 amdgpu 0000:07:00.0: amdgpu: GPU reset succeeded, trying to resume
...(and similarly for kernel 5.9.0)

It is probably an off-topic, but it seems to be related to amdgpu driver, and I
don't know how to move forward (and somebody reported that ROCk 3.7 driver
works well with APU Renoir).
