Title:
All Bluetooth devices disconnect randomly and cannot reconnect on
Intel 7260
Status in linux package in Ubuntu:
Confirmed
Bug description:
I've been having issues with bluetooth on my laptop.
The problem is that sometimes all devices (wireless keyboard and
mouse) are suddenly disconnected. When I try to reconnect them
manually, nothing happens, although Bluetooth is shown as turned on.
When I turn it off, I cannot turn it back on - both using the GUI and
bluetoothctl.
I tried adding "btusb.enable_autosuspend=0" kernel option, but it did not
help.
After it happens, the only way to make it work again is to reboot or remove
the btusb module, load it back and restart bluetooth.service.
It was happening on Ubuntu 18.04.4 with kernel 5.3 and is still
present on 20.04.1 with 5.4 (fresh install, not an upgrade).
My bluetooth module is integrated in the WiFi card Intel 7260.
