Same problem with a SuperMicro Board X11SSH-F with Intel C236 Chipset and two sata disks.
Installing the server with bios sata mode "RAID" and a RAID1 configured in the Intel Raid bios (Ctrl+I), on a fresh Ubuntu install and also on updated Ubuntu 16.04.2 the server doesn't restart or shutdown, it hangs at "Reached target shutdown". Installing the server with bios sata mode "AHCI", so without configuring something in the Intel Raid bios, but configuring a RAID1 only direct at Ubuntu as mdraid, restart and shutdown work fine with fresh install and also with all updates to 16.04.2 as expected. May I ask, if this bug will be solved in the future, and if there is a timeline? We planned to buy a lot of this servers, install Ubuntu and put them in a data centre miley away, but we can't wait another year. It someone in Germany really is able and willing to solve this bug, I would be willing to lend our server for some weeks.
