Comment 15 for bug 561390

2.13 didn't work for me, but after trying out 2.14 from the PPA it booted up cleanly. I'm attaching the boot.log with --debug and /var/log/udev.

What Happened:
System booted and stuck at mounting /var and /local/mnt, continued booting after pressing S to skip

What I did:
Added PPA and upgraded to mountall 2.14, which then the system booted fully and mounted all LVM partitions without needing to press S.
