Hello, I'm encoutring a Kernel BUG as you can see here in kern.log : http://pastebin.com/EHE9xtBB the system seams to work corctly but slow. after few days it raise a high cpu load. the process Xorg do not stop and can not be killed (parent process is 1) the system do not reboot with standard "reboot" command, it have to be forced with "reboot -f" this bug do not appear with kernel stable 3.16.
