Next, I deleted all the images I had and switched over to the Daily
stream.  First, I downloaded ONLY 14.04 amd64.

Once that was ready, I ensured the Arch was set to amd64/hwe-u and again
attempted commissioning.

So using the 14.04 images only from Daily, I was able to successfully
commission using the hwe-u kernel according to the boot messages that
said it was booting ephemeral-ubuntu-amd64-hwe-u-trusty-daily

To verify this, I then deployed with the node set to amd64/hwe-u,
Default OS, Default Release (14.04LTS).  After deployment I confirmed
that it was running what appears to be 14.04.2 with a 3.16 kernel
(3.16.0-37).

  commissioning an IBM Power8 PPC server causes a periodic kernel panic.

  This happens intermittently and cannot be forcefully reproduced.

  The kernel version on the image is 3.13.0-27.50-generic according to
  the boot process.
