Public bug reported:
kernel : 4.2.0-27
onboard bluetooth controller : AR3011
The Bluetooth was working great. I deactivated the bluetooth via the indicator,
and then, impossible to start it. Neither from the settings bluetooth
interface, neither via hciconfig. The service was of course started without
problems.
The device was well recognized and started, could find which usb port and
everything. However hciconfig could not see it:
$ hciconfig -a hci0
hci0: Type: BR/EDR Bus: USB
BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
DOWN
RX bytes:0 acl:0 sco:0 events:0 errors:0
TX bytes:12 acl:0 sco:0 commands:4 errors:0
Of course I restarted the system, tried purging all bluetooth related packages,
tried installing blueman. Nothing would make it start.
Finally I found this thread of arch linux :
https://bbs.archlinux.org/viewtopic.php?id=171357
So basically I shut down the computer, waited a while, started the computer and
the bluetooth is functional again.
I will try reproducing the bug. I tried, but it did not happen again. Maybe
it's because I was listening music, lost signal, came back to the pc and closed
bluetooth.
Any thoughts of what is this caused by?
