This system does not use Partition Firmware. KVM uses SLOF.
The error is a Program Exception 700, which is an illegal instruction. The
address of the instruction in SRR0 is 0. Code is attempting to execute at that
address.

From LTC bug 116747 Comment 12 Paulo Flabiano Smorigo 2014-09-29 18:21:13 EDT
That exception is caused by a VSX exception (f40 at SRR0) in the release 13 of grub package. A new package (14) was released friday and fixes that problem.
From LTC bug 116747 Comment 16 Paulo Flabiano Smorigo 2014-09-30 14:33:41 EDT
grub is fixed in the ISO but in order to use this new version another package, debian-installer, needed to be rebuilt.
SO it looks like some patches were not forward-ported to grub-installer in 15.10
FYI: Another dup was LTC bug 116767, which was mirrored to LP 1375216.

This exception isn't the same as the VSX one. The SRR0 is 0 so I believe that it's something else.
I'm not aware of any patch that needs to be forward-ported to 15.10. All necessary patches are in place.
