Abhishek Ellore Sreenath, thank you for testing the mainline kernel. The next step is to perform a Ubuntu kernel commit bisect from 3.2.0.29 to 3.2.0.30, in order to identify the last good Ubuntu kernel commit, followed immediately by the first bad one.
Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Thank you for your understanding.
