Yeah, and while this is causing the panic this is not related to the display
corruption.

The garbage lines we see at boot seem to be displayed at the same time when=
 in
the log we have:

Yes, disabling the stack protection xorg works fine (no panic, but I still =
have
the display corruption at boot and on poweroff/reboot)
