Bug Description

I have an Atheros mixed WiFi+Bluetooth device which worked nice on a kernels prior to 4.4.0-127
But unfortunately after last upgrade (from 4.4.0-124 to 4.4.0-127) bluetooth is unable to start - no bluetooth indicator appears in notifications tray and no device could be discovered or connected to via bluetooth.

Tailing a syslog provides following lines, related to bluetooth:
May 27 12:15:16 K43T kernel: [ 228.102799] usbcore: registered new interface driver btusb
May 27 12:15:16 K43T kernel: [ 228.109562] Bluetooth: hci0: don't support firmware rome 0x1020200

Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174

BugLink: http://bugs.launchpad.net/bugs/1764973

commit f44cb4b19ed40b655c2d422c9021ab2c2625adb6 upstream.

    The Atheros 1525/QCA6174 BT doesn't seem working properly on the
    recent kernels, as it tries to load a wrong firmware
    ar3k/AthrBT_0x00000200.dfu and it fails.

This seems to have been a problem for some time, and the known
workaround is to apply BTUSB_QCA_ROM quirk instead of BTUSB_ATH3012.

Do you have the problem with latest mainline kernel?

I'm not sure which mainline kernel is a latest one, so i tried several versions:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.14-xenial/ OK
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.14-xenial/ OK
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.134/ OK
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/ Bluetooth not working
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17-rc7/ OK

I hope this will help.

I seem to have the same problem (Dell XPS L421X). Bluetooth failing on 4.4.0-127, but works on 4.4.0-124.

Happy to provide any logs/diags under each kernel if you let me know what would be useful.

Revert "Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174"

    Commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros
    1525/QCA6174") is causing bluetooth to no longer work for several
    people, see: https://bugzilla.redhat.com/show_bug.cgi?id=1568911

So lets revert it for now and try to find another solution for
devices which need the modified quirk.
