I have found the following in my syslog after system (or only X11?) lockup.
Lockup was caused by running screensaver 'starwars' after resuming system from
suspend-to-disk. I have also noticed small amount of garbage in the top left
corner of the screen (like on screenshot with Blender's window).
May 28 00:21:59 nout kernel: [drm:savage_bci_wait_event_shadow] *ERROR* failed!
May 28 00:21:59 nout kernel: [drm] status=0x00008b1f, e=0x8b2b
There was no other messages related to drm in syslog or Xorg.log
