--- Comment #11 from Hans de Goede (jwrdegoede@xxxxxxxxxxxxxxxxx) ---
Hi All,

What might help for those of yoy with a broadcom wifi/bt combo card is making
sure you've a so called patch-ram for your BT controller in place.

Run "dmesg > dmesg.log" shortly after a boot. Likely you will find a message
about missing firmware for the bluetooth in dmesg.log. If the bluetooth part of
your wifi/bt combo card is USB based (it likely is) you can find firmware files
for it here:
https://github.com/winterheart/broadcom-bt-firmware

Please try putting a firmware file from there (with the right name) under
/lib/firmware/brcm and then reboot. Please do a second:

dmesg > dmesg2.log

After the reboot with the firmware in place and check that the firmware now is
being loaded. Once you've confirmed that the firmware is being loaded, you can
check if the problem is now fixed.

Regards,

Hans
