Disabling multi-queue fixes it and allows it to boot.

I have not tested this in combination with the AHCI LPM policy change
Ben suggested as just disabling multi-queue Works Fine For Me.

This seems unwize. I saw the patches implementing runtime PM for MQ go
by and am firmly in the camp of not enabling the new way to do stuff
until it's (mostly) feature-complete with the old way.
