PSA: Linux kernel 6.18.5 breaks opencl compute on Intel

Post by muziqaz »

Hi,
It seems that kernel 6.18.5 (possible the whole 6.18 family) breaks FAH compute, which is based on OpenCL. Downgrading to 6.17.12 works fine.
Tested on Fedora43 B580

That's with AMD GPU drivers, I suppose. 6.18 works fine with Nvidia drivers.

Check the section this post is written :P You can't blame AMD drivers for Intel issues :D
