I think we're waiting on a snap of this for testing. We already tested
and confirmed it worked on a snap that ppisati built (see comment #6 and
comment #8).

Is it possible to push this to edge or some other track? I'm having
trouble sideloading a kernel snap with --dangerous. I get the following
error:
ubuntu@localhost:~$ sudo snap install
./dragonboard-kernel_4.15.0-43.46_lp1810797_arm64.snap --dangerous
error: cannot perform the following
And here is a kernel snap for testing:
http://people.canonical.com/~ppisati/lp1810797/dragonboard-
kernel_4.15.0-43.46~lp1810797_arm64.snap
hcitool has a problem accessing hci0 on Ubuntu core (at least, in my
tests), use bluetoothctl instead:
p-pisati@localhost:~$ sudo bluetoothctl
[NEW] Controll
** Description changed:
Impact:
Upon boot, no hci device is available to userspace, thus bluetooth
communication is not possible.
Defect analysis:
The root of the problem lies in these two patches:
$ git log --online drivers/bluetooth/btqcomsmd.c
