Today I tried the Xubuntu Xenial daily image and again (live usb), the system was not able to shut down. In the live session, selected the Xubuntu menu, shut down, when Xubuntu image appeared pressed [F1] to be able to see system messages, I got these messages at the end:
[OK] Stopped target Local File System. Unmounting /run/user/999... Unmounting cdrom.mount... Unmounting /rofs... Unmounting /sys/kernel/debug/tracing... Unmounting /tmp... [FAILED] Failed unmounting cdrom.mount. cdrom.mount [OK] Unmounted /sys/kernel/debug/tracing. [OK] Unmounted /run/user/999. [OK] Unmounted /rofs. [OK] Unmounted /tmp. [OK] Reached target Unmount All Filesystems. [OK] Stopped target Local File Systems (Pre). [OK] Stopped Create Static Device Nodes in /dev. [OK] Stopped Remount Root and Kernel File Systems. [OK] Reached target Shutdown. [202.959599] reboot: Power down And the system hangs there, it does not complete the shut down. It does not respond to any keypress, I have to keep the power button pressed to get the computer shut down. ** Changed in: linux (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1552985 Title: [Dell Inspiron 14 3000 Series] System hangs on poweroff To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1552985/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
