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

Maybe it's some race issue between iwlwifi and btusb, because I could also see
this error message framed by iwlwifi messages:
[ 9582.557934] iwlwifi 0000:04:00.0: L1 Enabled - LTR Enabled
[ 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

Is it still reproducible for you with Linux 5.5?
