The following two patches fix the bug 543617 on launchpad. The first patch is
a revert of a temporary fix of this bug. The second patch is a hack which
solves this bug. To resolve this issue without any side effects and
further ado, we can for now, consider the second patch for lucid.

However, there is another bigger patch by Jens Axboe which is
submitted as a fix for this regression/bug. We will pick this patch from
stable as and when it is released and at that point revert the second
patch in this series that is intended to fix the issue for now.
