I tried the new 4.4.0-r7 kernel.  Sadly, it failed to boot.  Jpg of screen attached.  It’s a little blurry.  Incase you have trouble reading it, the last few lines of text say:

rtc-generic rtc-generic: setting system clock to 2016-01-03 …
List of all partitions:
No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
CPU: 1 PID: 1 Comm: swapper/0 Not tainted 4.4.0-rc7-powerpc64 #1
Call Trace:
   …
Rebooting in 180 seconds..

In preparation, I did
    dpkg -i linux-headers-4.4.0-rc5-powerpc64_1_powerpc.deb
    dpkg -i linux-headers-4.3.0-powerpc64_1_powerpc.deb
    update-initramfs -u
    ybin -v

I already had made an entry in /etc/yaboot.conf that loads the appropriate kernel and initramfs

The root filesystem is on an LVM2 partition on a RAID1 array

Here’s /etc/fstab:
