Hi John,

Thank you for the finding.

But there is no process invoked explicitly from our end.

So is there something that we can check for this error ?

@paolo.pisati<mailto:paolo.pisati at canonical.com> and @ogra<mailto:ogra at ubuntu.com>:
We downloaded the xenial kernel that is used for Dragonboard410c prebuilt binaries as you mentioned earlier:
git clone git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/xenial

We added dtsi and firmware options in snapcraft.yaml.
Here is our snapcraft.yaml: http://pastebin.com/QBKLGkfu

We are getting wifi interface in the first boot console, and all the modules are automatically loaded (insmod) when rootfs is mounted.

It would be great if you can address the below issues / queries
(This would really get us going ahead):

1. "snap list" does not show any snaps.
However, we have observed that there are times when "snap list" shows
just core.snap. But this is very rare.

2. "snap install hello-world" gives this error: http://pastebin.com/HV4fWzGk

3. When we build the linaro linux kernel, once we generate the uImage,
we build the boot.img which has the DTB + uImage + cmdline args + initrd.

So if we want to change the cmdline arguments to kernel in Ubuntu-Core,
then how can we change it from snapcraft.yaml ?

Awaiting your reply.

Thanks & Regards,
