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 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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1552985 Title: [Dell Inspiron 14 3000 Series] System hangs on poweroff Status in linux package in Ubuntu: Confirmed Bug description: Xubuntu 14.04.4 LTS Linux 3.13.0-79-generic #123-Ubuntu SMP Fri Feb 19 14:27:58 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux When shutting down the system, it gets stuck on the Xubuntu splash screen. I have to press the power button for a while to have it shut down. This is a dual boot system: Windows 10 and Xubuntu 14.04. I updated BIOS version to A10 a couple of days ago. It hanged when trying to shut down from both Windows and Xubuntu. After installing the firmware update from http://www.dell.com/support/article/mx/es/mxbsdt1/SLN300281/EN, the computer shuts down correctly from Windows, but still gets stuck when trying to shut down from Xubuntu, no matter if using the "Shutdown" button or running "shutdown -h now" or "poweroff" from a terminal. I found a similar bug here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1341925?comments=all, but the solution mentioned there did not work for me, also, I don't have any problems when rebooting the computer, just when trying to shut down.
