I'm 99% sure that this is just the grub2 issue that is known and already
fixed upstream (and in 15.04).
Linux is setting one bit in the C-A-S vectors, grub2 is unsetting (or
v.v., I forget exactly) and so the negotiation fails and we reboot
continuously.
LTC Bug 111313 - LP1334793, closed in 14.10.
AFAIK, 14.04.1/2 do not support PowerVM, so this is only targetted to
14.04.3.

====================
Ubuntu 14.04.1 was installed on alp026p1 partition. Installation went fine, but the partition is not able to boot with installed disk. Partition keeps on rebooting without booting.
Here is the output from vterm console:

Ubuntu 14.04.1 is running as native partition on PowerVM. So there is no guest involved. On Alpine, only PowerVM is supported.

Hi,
I have recreated the issue on the partition now. Below is the snapshot
from vterm during partition reboots:

Ubuntu 15.04 works fine with Alpine on PowerVM as a native partition. The above problem is occurring only with Ubuntu 14.04 which is officially supported on Alpine. Here is the working Ubuntu 15.04 version working on another system.
