Hi,
the Bluetooth firmware sometimes fail to load during hci_power_on with
an Intel 7260 in a ThinkPad X240. Running Ubuntu 14.04 but with their
mainline kernel 3.15.1-031501-generic. Fails maybe one out of ten
times when resuming from standby.
Not sure if it's a Bluetooth bug or another part of the kernel. Do you
want me to file a bug report in the kernel Bugzilla?
