System works perfectly as expected.
Change to kernel 4.4.x or 4.5 and RAID 5 doesnt work. I am not sure whether
its actually RAID 5 at fault or if its the USB Attached SCSI driver uas.ko,
or maybe the host driver xhci-hcd.
Can you run 'git bisect' to try to track down the offending commit?
thanks,

Hi, I am unfamiliar with that command, when should it be run, and in what
directory?
Use it on the Linux kernel source git tree. 'man git-bisect' will
describe all about how to use it. If you have specific questions about
it after reading that, please let us know.
thanks,
greg k-h
I am sorry to disappoint you ... I know nothing of the git tree ... I am
just a normal user who knows a little more than usual but not that much
more ... i only download the source tarballs from kernel.org, i don't
use git ... so i don't know how else to help
thanks
