SRU Justification (Lucid):

Impact: Changes to ext4 which are part of 2.6.32.17 and we took in advance to fix other issues are causing a lockup regression when working with lvm snap-shots.

Fix: This patch, which is slowly making its way upstream, was verified to fix this problem and is also small and contained enough to be reasonably save. The patch has now hit upstream and is expected to be seen in stable soon.

Testcase:
Use lvm to create a LV, mount it and have it actively doing IO, then try to create a snapshot will hang without further IO being possible.
