mw2202 and mw2203 failed to install, after a reboot it cannot access the disks:
Loading Linux 4.4.0-1-amd64 ...
Loading initial ramdisk ...
Loading, please wait...
mdadm: No devices listed in conf file were found.
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/84100d13-cfff-4ebd-b5bb-f8f402ddf5f7 does not exist. Dropping to a shell!

Could you run a hardware check on both systems for broken disks/controller?
mw2200/mw2201 from the same set of hardware class worked fine and I also tried booting with an older kernel, so probably a hardware issue.
