There is a patch that seems to solve the issues now: http://git.kernel.org/cgit/linux/kernel/git/rafael/linux-pm.git/commit/?h=bleeding-edge&id=42341f87ba1bee4c5be95038c24abb69cbcf361a It has as of writing this currently made it into the linux-next tree, so it should (hopefully) make it into a release soon. ------------------------------------------------------------------------------ Transform Data into Opportunity.
