Bug Description
Build an image today with
$ sudo ubuntu-image --channel edge -o pi3.img pi3.model
$ cat pi3.model
type: model
authority-id: 4BKZlf4WMNBKgQf
series: 16
brand-id: 4BKZlf4WMNBKgQf
model: pi3
architecture: armhf
gadget: pi3
kernel: pi2-kernel
timestamp: 2016-09-
...
Once flashed to sdcard and booted on the Pi3 it crashes again and again in the same place (__uart_start -> __dabt_svc) without doing anything. Device can't be used afterwards as this crashed the whole system. Reduced cable connections to just HDMI and power but no change.
See attached picture.
Kernel snap is pi2-kernel_15.snap

I've reproduced it just once using today's daily image[1] - i've flashed the image many times(~10 times), but i've got the panic on the screen only once, right before it should print "Press enter to configure" text.
