Public bug reported: The symptoms for this bug are very similar to those of #1396213: booting (a freshly installed wily VM) drops me to the (initramfs) prompt because the root filesystem (root=/dev/mapper/VG-root) cannot be found. Typing "vgchange -a y; exit" at the (initramfs) prompt allows the boot to continue normally.
The reason I'm filing a separate bug is that the discussion of #1396213 blames the problem on LVM snapshots and my setup does not have a snapshot: it happens on a system freshly installed using d-i, on the first reboot after installation (and on all subsequent reboots so far). As a result, I am not sure the root cause is the same. I've tried rootdelay=120 but that did not help.
