i915 GPU Hang on Atom x7-Z8750 with kernel 5.9.1 using Xorg

GPU HANG: ecode 8:1:85dffff9, in Xorg [427]

Hang occured coming from cold boot running firefox on xfce/xfwm4 on Xorg. Hang meaning frozen video/input while sound is running. Machine recovered after some seconds. Switched to VT and back. Image frozen but pointer could move. I will further observe the behaviour together with suspend2ram js webgl heavy browser.
