Comment 10 for bug 1339249

I had the same problem: boot hangs after "starting enable remaining boot-time encrypted block devices [OK]"

Triggeredby Marshall Sorenson's remarks, I checked /etc/fstab and found a duplicate entry (two lines trying to mount the same device) that I had accidentally added myself. After removing one of the entries, the boot process runs normally.

This confirms that the problem is probably related to a bad fstab configuration.
