This has been fixed in commit
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=dccd547e2bf2c01a13c967ae03a705338394fad6
Could you apply that patch on top of the current kernel source package
and test, whether it fixes the problem for you? If so, it could be
integrated into a kernel update for a point release.
