Comment 20 for bug 1335642

I've just seen this infinite loop in 16.04 with kernel 4.15.

For me, this was just a leftover because I was transitioning from software raid to btrfs raid. Therefore, I had commented out the old software raid definition in /etc/mdadm/mdadm.conf. Which in turn brought me to the loop problem.

Can't the boot process just continue as long as long as no raid is defined in mdadm.conf? In any case, there should not be a reason to loop here because it is unlikely that mdadm.conf changes during boot.
