Perry, yes, I'm still working on this to backport the patches to 3.19 kernel. But, I can not successfully reproduce this issue on the machines I have. Could you help to try if the kernel fix the issue? http://people.canonical.com/~acelan/bugs/lp1646537/
The kernel is a little bit older than the latest one, so please make sure to boot the system with the right kernel.
