No one has responded to my effort to convert this bug report into an SRU
request so I did the only thing I know, I opened LP: #888069

Title:
  grub2 fails to boot or install when an LVM snapshot exists

Status in “grub2” package in Ubuntu:
  Fix Released
Status in “grub2” package in Debian:
  Fix Released

Bug description:
  SRU Justification:

  Impact: When /boot and / are in an LVM VG and a snapshot is made of an
  LVM LV in that VG the system will not boot and grub can not be
  modified (updated, reinstalled) until all snapshots are removed.

  Testcase:

  Binary package hint: grub2

  Steps to reproduce:

  - (Lucid beta2 installed from CD)
  - Take a snapshot of any volume
  - on reboot:
    error: fd0 read error.
    error: no such disk.
    grub rescue>
  - Use the rescue cd to get a root shell
  - Remove the snapshot and reboot
  Now, the system boots. Create a new snapshot to repeat.

  The system has 2 SATA disks in mdadm RAID1 configuration with 1 lvm
  volume on top and no 'normal' partitions.
