[Bug 1425699] Re: kernel panic on IBM Power8 PPC MAAS ephemeral image
We ran into this while setting up an OpenStack cloud using IBM POWER8
machines. Unfortunately, hwe-v for Trusty isn't available
(LP:1504066) but hwe-u does indeed fix the "Oops: Exception in kernel
mode, sig: 4 [#47]" boot loop we ran into.
Since it's been advised here, and in several other bugs that
POWER8/ppc64el doesn't work with the main Trusty 3.13 kernel, perhaps we
could make MAAS images default to hwe-u and above for ppc64el?

kernel panic on IBM Power8 PPC MAAS ephemeral image
Status in maas-images:
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.
