Public bug reported:
I keep running into issues with booting on a 2013 Macbook Air. After
grub, the kernel and initrd load and the system then just hangs with a
blinking cursor.
Removing the "quiet" and "splash" options shows me that the kernel hangs
bringing up SMP, just as in bug #1197451 which has been marked Fix
Released already (some time ago, actually).
I get exactly what was mentioned in the comments about SMP hanging and
have had to manually inject nosmp into the boot command when I boot the
machine.
