Comment 97 for bug 984265

Became fine again on Saucy, now running Trusty without issue. The fact that this comes and goes with varying kernel families tells me this is tied into the kernel somewhere... but in any case, it's working now and I really don't care to fight with this any more (this is actually the second long-running bug I've had about this issue, and countless production, devel and test kernels attempted with varying degrees of success.
