I have set RESTORE ON AC/POWER LOSS option to POWER OFF so nop, but I have noticed something. When I set USB 3.0 Controller option in UEFI to DISABLE, everything is fine - computer goes power off as it should be, but I need this option ENABLE 'cause of performance.
This command: $echo -n "0000:00:14.0" > /sys/bus/pci/drivers/xhci_hcd/unbind && poweroff works as well. My USB tree in attachment as well as lspci. I think this upstream XHCI bug. ** Attachment added: "lspci and lsusb -t" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1579542/+attachment/4686399/+files/data -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1579542 Title: My computer reboots instead of shutdown Status in linux package in Ubuntu: Incomplete Bug description: Really basic operation - I go to drop-down system menu and choose "Shut down...".
