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...
I'm attaching Xorg.0.log file
Best Regards Krzysztof Grygiencz
