[Bug 1652504] Re: Recent updates broke Ubuntu on Raspberry Pi 3

[Markus Birth]

Upon further inspection: The flash-kernel from the rpi3 PPA
https://launchpad.net/~ubuntu-raspi2/+archive/ubuntu/ppa-rpi3 is only
published for Xenial and there, the boot script sets the fdt address to
0x100 instead of 0x2000000. And that works without explicitly loading
the fdt.

So it seems I had the "old" flash-kernel from before upgrading to
Yakkety and that worked. The new version tries to load the fdt from
0x2000000 where it isn't located.

Bug description:
  Hello,
  I've been running Raspberry Pi 3 with Ubuntu as described here https://wiki.ubuntu.com/ARM/RaspberryPi

  I've installed Ubuntu 16.04 and then upgraded to 16.10 and have been
  using this setup successfully since October up until last week.
  Unfortunately one of the latest kernel updates broke the installation
  and I found out the same happened for Ubuntu 16.04 LTS - and therefore
  I can no longer run up-to-date Ubuntu installation (with updated
  kernel) on my RPI.

  I am getting this error:
  Error image is not a fdt - must reset the board to recover

  I also tried this but it didn't help me:
  https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=168838

  Now I know running Ubuntu on RPI3 this way is not officially
  supported, but since Ubuntu Snappy is supported I thought someone here
  could know what is going on.

  Thank you very much.
