git bisect log

Error Description:
Since Kernel 5.1.x i had several GPU Hangs with my Hardware.
Typically when playing Video in mpv or using Chromium-Browser.
GPU Hang results in visible Lag/short hang/ not updating of the Desktop-UI
(KDE).

Regression because:
Using LTS Kernel 4.9.x does not have theses issues with the same userspace.
5.0.x didnt have these issues either iirc

System Hardware:

- CPU: Intel 3770 
- Mainboard: Intel DZ77RE-75K
- Dual Monitor (HDMI and mini-Displayport)

OS: Arch Linux 
with linux , linux-mainline, linux-lts packages,
a custom linux-bisect AUR package to test versions locally

I hope I didnt make an error with bisection.

Bisect Log output -> attachment
other dmesg/sysfs error txt -> attachment
