If the machine is booting (just with a blank screen), then enable
drm.debug=0xe, and check that it is being written to the system log
files. Then boot into the broken setup, reboot and grab the debug
messages saved from the previous (broken) boot.
Otherwise we shall just wait for the opportunity to log in with a second
machine and look for telltales before beginning exploratory surgery.
