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 reference for solution: https://bugzilla.kernel.org/show_bug.cgi?id=153281 ** Bug watch added: Linux Kernel Bug Tracker #153281 http://bugzilla.kernel.org/show_bug.cgi?id=153281 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1530405 Title: NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s!
