Dear Sir,

I'm using ArchLinux distribution. After kernel upgrade form 4.19.14 to 4.19.15 my X environment stopped working. I have AMD HD3300 (RS780D) graphics card. I have bisected kernel and found a failing commit:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v...

This is a false positive, you should skip that commit. It will not impact the GPU driver for your specific GPUs. My advice is to first bisect on drivers/gpu/drm/radeon only.

Cheers, Jérôme
