dmesg output
The following kernel works fine with my i915 GPU (5.6.14-1). However, the
latest kernel 5.7+ (kernel-default-5.8.7-1.2.x86_64) causes my GPU to hang and
it flickers and can never login. Switch back to 5.6 and it works fine.
There have been other reports on Fedora with the same thing.

I have attached my dmesg output. I use the zap option to kill the xorg server
and kdm comes up just fine most of the time. Trying to login is no good though.
Also I can ctrl-alt-f2 to go on command line just fine. So it seems to be xorg
with the new kernel.
