[drm:amdgpu_fill_buffer [amdgpu]] *ERROR* failed to pin userptr
I'm running Folding@home 7.6.13 on kernel 5.11.19 (Gentoo, distro kernel) and ROCm OpenCL runtime 4.1.0. After some good hours (almost a day) the following starts appearing in dmesg:
mai 11 12:46:44 optiplex kernel: [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* failed to pin userptr
mai 11 12:46:44 optiplex kernel: amdgpu: init_user_pages: failed to validate BO

mai 11 12:46:44 optiplex kernel: amdgpu: init_user_pages: failed to validate BO
with varying results. Sometimes the Folding@home aborts the tasks but everything else appears OK, other times the folding continues with no apparent problems, but applications like Firefox render incorrectly in maximized mode (a smaller window works OK).
I followed the steps listed by this rather old documentation to collect what I hope to be useful information. 20210511.zip
