I'd like to perform a bisect to figure out what commit caused this
regression. We need to identify the earliest kernel where the issue
started happening as well as the latest kernel that did not have this
issue.

Can you test the following kernels and report back? We are looking for
the first kernel version that exhibits this bug:

v3.11.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.4-saucy/
v3.11.5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.5-saucy/
v3.11.6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.6-saucy/

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

Thanks in advance!
