The firmware version of intel/ibt-18-16-1.sfi of recent series are:
* trusty: X
* xenial: REL0186 (affected)
* bionic: REL0201 (affected)
* cosmic: REL0329 (working)
* disco: REL0420 (working)
So currently only Bionic/Xenial are affected, and we don't have 9260
support in Trusty ever. Planning to upgrade firmware in Bionic & Xenial
to REL0329 as Cosmic does.

Bluetooth: hci0: request failed to create LE connection: status 0x0c

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://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1829737
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://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/intel
, power off the device completely and power on, then have a check on
bluetooth pairing.
