GPU hang trying to run OpenCL kernels on x86_64

[luis.p.mendes@xxxxxxxxx (Luís Mendes)]

Hi Michel,

No, I haven't tried the exact same versions of Mesa, nor libclc, nor
LLVM on x86, however on armhf I have been able to use several
combinations of Linux kernel versions and mesa versions which are able
to run the OpenCL kernels in question. I will try to see if the same
happens with the exact same Ubuntu 18.04 LTS base installation on
armhf, but won't be able to test it today.
