Comment 18 for bug 906358

Same problem: First a U11.10 installation into a 'normal' partition, all fine.

Later I set up a Logical Volume (actually using CentOS, which is also installed on the machine). I installed lvm2 in Ubuntu and added the path to the LV in /etc/fstab. The Logical Volume is available after boot, no error messages, but a 60 sec boot lag, which is also visible in dmesg:

My computer has a really fast SSD, so it is not a slow external (net) disk which causes the delay.
