Kernel 4.14 bluetooth problem [SOLVED]
I’ve upgraded my Manjaro kernel from 4.9.65 to 4.14.2 today and suddenly my bluetooth mouse stopped working. The adapter is Intel Wireless 8260 on Lenovo T460s laptop. After some searching I stumbled upon this kernel bug, but fiddling with firmware didn’t seem like an exciting prospect.
Thankfully, I’ve found solution in this thread on Manjaro Forums. Seems like the bug is there at least since kernel 4.13.2:
sudo nano /etc/modprobe.d/iwlwifi.conf
options iwlwifi bt_coex_active=0
After reboot the mouse is working fine with Wi-Fi turned on, audio receiver is yet to be tested.
UPD: bluetooth audio receiver is working fine too.
