It certainly is. This is the same problem as the first case reported at http://bugzilla.kernel.org/show_bug.cgi?id=10882. There is a patch in -mm for it already (2fde9f7a0faabe821b31ccd982d482c21f7c503f), posted here: http://marc.info/?l=linux-kernel&m=121486328013470. Hopefully that should fix the problem for you.
