[SOLVED] Bluetooth does not work after suspend and resume

[FroL_Onn]

I have
Bus 002 Device 005: ID 03f0:311d Hewlett-Packard Atheros AR9285 Malbec Bluetooth Adapter
on my HP probook.

For some reason after suspend and resume bluetooth is turned off and nothing helps me turning it on. Neither

Code: Select all

systemd restart bluetooth

, nor

Code: Select all

modprob -r btusb; modprob btusb

does the job...

Here is my kernel .config.
I use Gnome 3.18.
Here is my emerge --info

Have anybody experienced this problem too?

EDIT:

OK. It turned out, installing linux firmware fixed this. Not 100% sure as I've also rebuilt the kernel a bit, but after finally after installing linux-firmware package and several days of flawless testing I think this is it!

I am confused.

Could installing linux-firmware package have solved this issue?
I have tried suspending and resuming 3 times now and everything works great.

[Not now, John!]

In my case (Toshiba Satellite L50-A-1CD) unloading kernel module btusb and loading it again restored bluetooth device.
To make it permanent I created /etc/pm/sleep.d/50bluetooth:

Code: Select all

#!/bin/bash
case $1 in
	hibernate)
		modprobe -r btusb
		;;
	suspend)
		modprobe -r btusb
		;;
	thaw)
		modprobe btusb
		;;
	resume)
		modprobe btusb
		;;
	*)
		logger -t "TEST" "Somebody is calling me totally wrong."
		;;
esac
