Hi Rainer,
I think it's safe to say that commit
dd551ab7b47ace14753b0d73f79437cc35adcf6b introduced this regression.
I'll open an upstream bug for this and request it be reverted in Quantal
until a fix is available upstream.
Thanks so much for your help with this bug!

@Rainer,
It appears commit e19ebcab01cc130fa will fix this bug. It has been
submitted to linux-stable and should be in v3.5 soon. I'll build a

Hi Rainer,
It appears commit dd551ab7b47ace14753b0d73f79437cc35adcf6b introduced
the regression. I tried a revert of this commit, but it looks like some
work will need to be done to get commit to revert cleanly.
I'll update you shortly when a test kernel with this commit reverted is
available.
Sounds good Joseph. Nice to know that you've nailed it. :) Thank you
