Hi,
In trying to diagnose a problem with bluetooth-audio on my laptop, I've spotted that the firmware is failing to load.
The bluetooth related output from dmesg is:

The firmware two files mentioned are installed in /lib/firmware/intel and are successfully loaded by a 3.17.6 kernel:

Sorry, I accidentally clicked the send button when I meant to save the mail as a draft when I had a moment of
inspiration about what the problem might be.
In 3.17.6, btusb is a module whereas it's built in in 3.18.0, so rootfs may not be mounted. Switching back to module.

this is pretty much clear. The filesystem where the firmware is located is not yet mounted. Build the btusb.ko driver has a module.
