Booted via grub-n-iso shutdown works for me, but not when the pendrive was created by cloning the current Lubuntu Xenial i386 daily iso file,
xenial-desktop-i386.iso Today I tested with USB-creator-gtk 0.3.2 and mkusb, but can get the same result with other cloning tools, e.g. gnome-disks, dd. In other words, my live drive is affected when booted from a cloned system, but not from a grub-n-iso system made from the same iso file. I suspect that this bug is the same or closely related to the bug that also affects virtual machines, https://bugs.launchpad.net/ubuntu/+source/casper/+bug/966480 It is described as a race condition by Chris Bainbridge: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/966480/comments/58 -o- Details: I tested this in a laptop bought 2013 (that I am often using for iso testing), http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/ and in a desktop computer with the following motherboard bought 2008, http://www.asus.com/Motherboards/M2NVM_DVI/ A Sandisk Cruzer blade 4 GB USB drive cloned to a 'live-only' system with USB-creator-gtk 0.3.2 and mkusb is affected by this bug in both those computers. The same USB drive made into a grub-n-iso system with the same Lubuntu daily iso file according to the link http://ubuntuforums.org/showthread.php?t=2259682&p=13302278#post13302278 or made into a persistent live drive with mkusb according to this link https://help.ubuntu.com/community/mkusb/persistent can be shut down or rebooted properly (so these systems booted via grub are not affected). PS. Until this bug is squashed (and in other cases where a linux system is unresponsive)I recommend SysRq + r e i s u b described in the following link https://en.wikipedia.org/wiki/Magic_SysRq_key DS. -- 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: Incomplete 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.
