Thank you for testing! Unfortunately, it looks like your reboot issues aren't related to the xHCI issue that Giorgos and littlebat reported, since that code was added in 3.12. Please file a separate bug, so that we can close this one. I would also suggest you see if there's a BIOS update for your system and try that before filing the bug. Sorry I couldn't be more helpful.
