I'm not sure it's regression issue or not, but it's also happen on 3.19 kernel ( 3.19.0-27 ) "with" HDMI plug, if I unplug the HDMI and test it again then the system can be shutdown without hang.
so the different between original kernel and bpo 2.2 is : bpo 2.2 encounter shutdown hang "without" HDMI plug and both encounter this issue "with" HDMI plug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1490895 Title: Skylake/Broadwell/Haswell: No HDMI audio jack detection in D3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1490895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
