When I try to install Ubuntu Precise Pangolin using LVM for my filesystems, it gives me this warning:

  Could not stat device /dev/mapper/hostname-root - No such file or directory.

If I select "Retry", everything works.

It appears that the LVs are created, but their entries in "/dev/mapper" don't exist yet when the rest of the system tries to use them.

I will attach a short video with some more information, along with the fix that worked for me.
