This issue can be reproduced in 3.2.0-133 in proposed and 3.2.0-131. So it should not be considered as a regression.
We didn't spot this issue before, until I'm testing 3.2 kernel on one of the laptop (CID 201307-13930) in Cert lab this cycle.

We didn't spot this issue before, until I'm testing 3.2 kernel on one of the laptop (CID 201307-13930) in Cert lab instead of using our regular regression-testing test pool from kernel team this cycle.
