Ok, I think I am seeing a bug very similar to this one reported by Loic
Poulain:
http://marc.info/?l=linux-bluetooth&m=143220351521634&w=2
("bluetooth-next HCI user channel issue")
I have the same symptom of bluemoon hanging, and I figured out that I can
recover the system without rebooting by forcing hci0 down again. "hciconfig
hci0 down" takes about ten seconds to return, and then I have a 0xfc3f
timeout in dmesg:
[ 5563.562554] Bluetooth: hci0 command 0xfc3f tx timeout
[ 5571.557618] Bluetooth: hci0: turning off Intel device LED failed (-110)
This is the same error Loic was getting, I assume because the commit in
question has now made it into my kernel (4.2.0-rc4).
