I am experiencing exactly the same problem since I upgraded to Lucid two days ago.
Seems to be related to the following issue in Lucid: https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/527666 The boot process hangs with the following message: The disk drive for /xxx is not ready yet or not present. Continue to wait; or Press S to skip mount or M for manual recover /xxx is any partition on LVM. I have to execute the following procedure to get to the GDM screen: 1. Enter M (for Manual Recovery) 2. Execute "mount -a" which mounts all filesystems on LVM without problems. 3. CTRL-D to close the shell and continue with the reboot. Check the bug report mentioned above for detailed information on the issue. -- LVM - /var failed to mount during boot https://bugs.launchpad.net/bugs/561390 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
