Package: firmware-iwlwifi
Version: 20170823-1
Severity: normal

I have a 4th generation Lenovo Thinkpad Carbon X1 with Intel 8260
wifi/bluetooth:

04:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)
	Subsystem: Intel Corporation Wireless 8260 [8086:1130]
	Flags: bus master, fast devsel, latency 0, IRQ 130
	Memory at f1100000 (64-bit, non-prefetchable) [size=8K]
	Capabilities: <access denied>
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

When trying to use my bluetooth mouse yesterday, I couldn't get it to
connect successfully. I tried again today, and after a lot of hassle
turning Bluetooth on and off in GNOME and pressing the mouse's connect
button it connected. But it only worked for a short time, about a
minute, then the mouse stopped working even though the BT config said it
was connected. This kept happening each time I reconnected.

I've replaced the package with 20161130-3 from stable, and bluetooth
seems to work correctly with this older firmware. But I had the same
problem a few months ago (which I commented on at a now closed bug
<https://bugzilla.kernel.org/show_bug.cgi?id=190831>) with kernel
4.9.6-3 and firmware-iwlwifi 20161130-2, so it seems like something that
was changed between 20161130-2 and -3 cured this problem, but it has now
regressed.
