I might have the same bug

I does not append with Mesa git from mid august but a version from beginning of
September do it.

System boot, splash screen turn on, I login in KDE, sometime it fail and return
to login (X crash).

With it work, doing stuff that require 3D card will sometime work or do
graphics corruption and crash the system. When games work, it usually crash
after not so long.. Even opening the KDE menu can trigger the crash, when that
append, the mouse usually work but nothing else (can't toggle numlock for
example). Using magic keys usually work to reboot the system.

Kernel 4.12
DDX GIT
Mesa GIT
libdrm from 22 Jul (might be old but mesa don't complain when I build it.

Video card is a Polaris 10 card (RX480)


/var/log/message get flooded by these when I open an opengl context:
