This looks like a problem in how the kernel loads the modules; the ath3k and btusb modules appear to be in SUSPEND_MODULES in the pm config, and is not loaded in the correct way, which may be the cause for bluetooth going down.

However, after hibernation and subsequent resume, the Bluetooth device is off again, and it is missing from hcitool dev and rfkill list.
