Ubuntu – Stuck on reboot and shutdown

I had a similar problem with a Dell XPS 15z which I resolved by adding acpi=noirq to the kernel arguments:

sudo editor /etc/default/grub

set

GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet splash"

then

sudo update-grub

Note that previously I had been using acpi=off, which permitted me to boot, but not shutdown. Without any acpi flag, I was not able to boot.

Ubuntu – Ubuntu 14.04 wont shutdown or reboot

For others with this problem, I was experiencing the same thing. I didn't even have to try this (which was my "okay, i'll deal with it this way" option).

After a Google search I found another solution, which is to go into /usr/share/dbus-1/system-services and rename the file org.freedesktop.ModemManager1.service to anything else. I called mine thisfilebreaksmycomputer.service. I had to sudo the mv command to do this.

Upon renaming I was able to successfully shut down and boot up without any issues!
