Hello! I have Lenovo Thinkpad T460s with Wifi/BT chip Intel 8260. There is a problem with bluetooth - device disappears from bluetoothctl list. I could see such error message in the log file:

[ 9077.430266] Bluetooth: hci0: Failed to send firmware data (-38)
If I manually rmmod btusb && modprobe btusb, I could see:
[ 9220.767742] usbcore: deregistering interface driver btusb
[ 9225.687528] usbcore: registered new interface driver btusb

and everything will start working again. I'm using linux-firmware-20160331.

--- Comment #1 from Yaroslav Isakov <[email protected]> --- Maybe it's some race issue between iwlwifi and btusb, because I could also see this error message framed by iwlwifi messages:

[ 9582.559428] iwlwifi 0000:04:00.0: can't access the RSA semaphore it is write

It seems that bluetooth breaks on "Bluetooth: hci0: Waiting for firmware download to complete" step
