Fresh Ubuntu 12.04.1 amd64 install with the following partition layout / lvm setup:
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sr0 11:0 1 1024M 0 rom
sda 8:0 0 20G 0 disk
├─sda1 8:1 0 243M 0 part /boot
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 19.8G 0 part
  ├─u1204--64-swap_1 (dm-0) 252:0 0 1020M 0 lvm [SWAP]
  ├─u1204--64-root (dm-1) 252:1 0 7.6G 0 lvm /
  └─u1204--64-usr--local (dm-2) 252:2 0 11.1G 0 lvm /usr/local

The installation works as expected and there are no imminent issues during normal usage.
The issue is with the recovery menu. If someone boots into a rescue entry in the boot menu the rescue menu appears as expected but all entries that remount the root volume rw will hang on mountall.
