Bug Description
[Impact]
Intel Wireless-AC 9260 Bluetooth doesn't pair to Bluetooth 5.0 HID
devices.
[Fix]
Bluetooth FW Build REL0329 or newer is known to have fixed this problem
on Cosmic, and for Disco we have REL0420. On Bionic and Xenial it takes
a firmware backport from upstream commit
c2d8f1b7f820b31
conflicts in the WHENCE file.
[Test Case]
Verified on hardware platforms with Intel Wireless AC 9260 installed,
e.g. Dell Precision 7530. Copied the two blobs to /lib/firmware/intel
and power off the device completely to trigger firmware reload at the
next boot.
[Regression Risk]
Low. Tried following kernels with REL0329 firmware blobs:
* 4.4.0-154-generic: Xenial, WiFi/Bluetooth doesn't work
* 4.8.0-58-generic: Xenial, even doesn't boot to console
* 4.10.0-42-generic: Xenial, WiFi/Bluetooth doesn't work
* 4.11.0-14-generic: Xenial, WiFi/Bluetooth doesn't work
* 4.13.0-45-generic: Xenial
* 4.15.0-54-generic: Xenial, Bionic
* 4.15.0-1043-oem: Xenial, Bionic
For those WiFi/Bluetooth doesn't work versions, WiFi/Bluetooth doesn't
work even with current firmware blobs shipped in Xenial's linux-firmware
REL0186. So overall, these updated blobs are only loaded by hardware
requires them, and they doesn't bring harm to known working
configurations.
================ Original Bug Description ================
Same problem exactly as encountered with Intel 9560 is also happening with Intel 9260.
Update to linux-firmware 1.173.8 did not fix the problem.
Everything is working fine when using 4.15 kernel, but not for 4.18+ 5.0+.
Reference problem:
https:/
You-Sheng Yang advised to do this by email and it fixed my issue, so I think the 9260 driver would need to be updated in the bionic branch (it seems to be updated in newer branches).

Basically you should try copy the latest firmware (ibt-*) under
https:/
, power off the device completely and power on, then have a check on
bluetooth pairing.

Hi @vincentbou, I'll need you to run `apport-collect 1835449` in the first boot after completely power off again. I need to know which firmware blob, probably in the name "intel/ibt-*", to be updated.
