I have the same problem with 3.13.0-46. The P9D-X mobo simply does not power off if WoL is enabled. I tried to go back to 0-45 and 0-44 but they all show the problem. The last working kernel is 3.13.0-43. We are now 3 kernel later and the problem is still there.
My lsb_release -rd shows: Description: Ubuntu 14.04.2 LTS Release: 14.04 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-trusty in Ubuntu. https://bugs.launchpad.net/bugs/1411361 Title: kernel 3.13.0-44 doesn't poweroff (shutdown) with WoL enabled Status in linux-lts-trusty package in Ubuntu: Confirmed Bug description: This bug is similar to Bug #1346269. I successfully used to use WoL (wake on lan) since Sep. 2014 with Ubuntu 14.04.1 LTS on my ASUS P9D-X Server. After I updated to kernel 3.13.0-44 this feature broke and my server always restarted when I issued a 'poweroff'. I disabled WoL for PCI and PCIe in the APM settings in BIOS and poweroff worked as it should, but then Wake on LAN is gone which is not a nice setting for a server in a closet. So I reverted to 3.13.0-43 and the problem was gone. Thus something in kernel -44 must have changed to the worse. Please check what has happened and fix this issue again in upcoming kernel releases. #lsb_release -rd Description: Ubuntu 14.04.1 LTS Release: 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1411361/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
