after re-testing since a while back, now with 16.04.2, I was able to isolate that acpi_osi parameter solves the shutdown issue from nouveau "failed to adjust lnkctl speed"
update grub with:
GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=\"!Windows 2015\""
* I removed the quiet splash just to see boot logs in progress * this worked with 16.04.1, I just didn't figure it out then
