System just hangs on "Will now halt" or "Will now reboot". Different combinations of kernel params "acpi=force", "acpi=off" etc didn't help. I've also tried to boot from liveUSB(14.10) with the same result. After some investigation I found that shutdown, reboot etc actually works with kernel 3.13 from previous ubuntu version, but not with kernel 3.16(default) or 3.18 so it is quite definitely a kernel bug.
