Added this to maas-images. From chats with Mike, I believe that the
Vivid ephemerals are stable on Power8.
I suspect that what's happening (I have not looked too deeply into this
so this is just a guess for now) that the ephemerals are built at GA
time, and after that point only the filesystem tarball is built for the

14.04.0 ephemeral to do so.
Unfortunately, We can not use vivid ephemerals to certify Trusty, so we
need a full stack of Trusty images for the power machines.
This bug is currently gating PowerNV certification so I consider it a

kernel panic on IBM Power8 PPC MAAS ephemeral image
Status in Maas image builders:
Status in linux package in Ubuntu:
Status in linux source package in Trusty:
The kernel running on the 14.04 ephemeral image for MAAS when
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.
Attached is the boot process log with the kernel panics.
