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:

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

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.
