Do you happen to know the last good and first bad kernel versions? If so, I can perform a bisect to identify the commit that caused the regression.

If you don't know the first bad kernel, can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug:

v3.5.7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.7-quantal/
v3.6 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/
v3.7-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc3-raring/

You don't have to test every kernel, just up until the kernel that first has this bug.
