@Marc, if you are willing to bisect, we first need to see if this regression was introduced by and upstream commit. 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: v3.13.9: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.9-trusty/ v3.13.10: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.10-trusty/ v3.13.11: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11-trusty/ You don't have to test every kernel, just up until the kernel that first has this bug.
