We found testing with the latest Xenial kernel (4.4.0.62.65) from https://launchpad.net/~canonical-kernel- team/+archive/ubuntu/ppa/+build/11278866 fixes this issue - no firmware updates required. We did also test with just the latest firmware updates, and that did not fix the issue. Latest firmware + 4.4.0.62.65 also works.

The install eventually fails - it looks like the writes back to one of the disks starts to fail for some reason. Servers are targeted with Xenial and the release 4.4 kernel (no HWE).
