Please attach the output of dmesg with 4.20 and 4.19.

Can you bisect?

sorry cant bisect even if i could it requires a lot of time,since it is
graphical and the laptop uses only amd gpus,it is likely a commit to the amdgpu
that caused it.

kernel 4.20rc5 completely broke on my laptop cannot boot or look at logs it
freezes after grub with cursor blink and cpu fan at 100%

that was an issue with the kernel fedora mainline repo, kernel 4.20rc5 boots on
my laptop on archlinux, but the mouse pointer issue remains

A workaround that works is to enable software cursor in Xorg,
i edited 10-amdgpu.conf and 10-radeon.conf
and added:

Option "SWCursor" "True"
