I have the same thing happening in my T440s running Kubuntu 13.10, is there anything I can provide for you that can help solving this? I've installed the version 3.10.27-031027-generic of the kernel and it behave better for a couple hours, now its doing the same thing bringing down the hci0 device, one thing that it's better with 3.10 kernel is that when it gets disconnected the device still shows when running "hciconfig dev" but when running 3.11 the device is gone!
Let me know if I can help getting something else.
