Here's a discussion thread regarding this annoying bug ... https://lkml.org/lkml/2012/2/6/20 I've placed a link to an upstream fix in the URL field, which can probably be found in the latest 3.4 RC by now. I've applied the patch to 3.3.1 with success and it should also apply to all current 'stable' kernels. Ubuntu have already picked it up for their 3.0 tree.
In svn for the next 3.3-rX release
Released in gentoo-sources-3.3.2
