[RX 480] - Orca OpenCL 20.10.1048554 fails to function and causes GPU faults
I am running Arch Linux, with a third party kernel, linux 5.6.5-10-tkg-pds, and attempted to update my opencl-amd package to the latest 20.10.1048554 release, which, just like the 20.10.1028677 early beta release, causes my GPU to lock up.
Here is my system log since boot, which includes the GPU faults triggering in Blender: journal.txt
The package is somewhat special, in that it installs the OpenCL drivers to the system /usr/lib folder, and that it modifies the Orca driver to refer to the AMDGPU-Pro supplied libdrm, under the modified name of libdrm_amdgpo.so. I do not know if somehow replacing the kernel stock amdgpu modules with the dkms modules included with the amdgpu-pro package will fix this, and even if it did, I have no idea how reliably I could package that together.
