Fixed in 5.3.5, now Blender runs correctly under OpenCL without segfaulting; clinfo is still crashing, but that's probably a program issue and not a OpenCL one now. |
Created attachment 285245 [details] OOPS kernel bug from querying OpenCL info on amdgpu Just discovered that if I try to query opencl info (tested with both Blender and clinfo from command line) the kernel throws an oops in dmesg and the calling process deadlock completely; the process will remain stuck until a hard reset. I was using the proprietary OpenCL AMD stack for Blender, but after removing it, the system threw the same identical error using clinfo. I just tried to downgrade to the latest 5.2.14 on my arch install, and everything started working again. Attached to this post is the oops log from the kernel.
