It affects kernels >= 4.8 on (as far as I know) any distro. I'm experiencing problems on both Fedora 24 and Ubuntu 16.10 running kernel 4.8 on a Dell Latitude E5450 with a Samsung 850 SSD. ** Bug watch added: Linux Kernel Bug Tracker #187061 http://bugzilla.kernel.org/show_bug.cgi?id=187061 ** Bug watch added: Linux Kernel Bug Tracker #151631 http://bugzilla.kernel.org/show_bug.cgi?id=151631 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1594023 Title: Poweroff or reboot hangs.
