Hi Joe

Thanks for the offer. There was an existing bug
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793 but that
has become out of date I think so I have opened a new one
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1491467

I have determined that the last of the 3.19 kernels is ok but the
first version in the wily tree that will build using fakeroot
debian/rules binary-headers binary-generic, which is

commit 636cdd7b2930ca2cdaf90eedd04fdb9fc7a8d5ec

    UBUNTU: SAUCE: (no-up) ubuntu: dm-raid45
