Can you please test whether 3.9-rc kernels are affected, too? We need
to know this since stable rules mandate that a regression is fixed on
upstream first. Once that's figured out we can backport a fix (if
3.9-rc works) or start working on a fix for 3.8-rc kernels first and
backport afterwards.

Thanks, Daniel
