I'm affected by this bug.
On latest BIOS update 2.17 problem persists.
Disable USB3.0 on Bios solves the problem.
Tried on kernels 3.16.0-29 and 3.18.2.
Running on Ubuntu 14.10, but I don't mind to install any other distro or version, either RHEL 7.0 or Ubuntu 12.04.02.
I'm able to help debug or provide any feedback if needed.
