Recovery mode boot works fine. When attempting to boot using integrated graphics, the syslog gets spammed with this sequence of errors over and over: Jul 19 19:07:09 polarimetric-MacBookPro acpid: 1 client rule loaded Jul 19 19:07:09 polarimetric-MacBookPro kernel: [ 26.475546] i915: Unknown parameter `modeset' Jul 19 19:07:09 polarimetric-MacBookPro gdm-simple-slave[1426]: Child process 1432 was already dead.

All module parameters are said to be invalid. After boot, attempting to insert a module results in the same error.
