== Comment: #11 - Gary M. Gaydos <gmgaydos at us.ibm.com> - 2015-09-29 14:37:05 ==
Steps to reproduce:

Install 15.10 beta 1 ppc little endian using multipath disks (in this case mpatha)
After the installation is finished no device is set as the first boot device.

The symptom is the same as launchpad bug 1486022 against 14.04.3.
Syslog from 1486022 and this bug are different however.  In 1486022 no
mpath devices are found.  In this bug mpath2a (the installation target)
has an unknown device type, and the volume group is not found.

Here's a snippet from the syslog

cat syslog |grep -a2 -b2 mpatha2
