After two days of installation, strangely my Ubuntu machine is restarting instead of shutdown from both desktop GUI and command line.

sudo shutdown -h now

sudo halt  # (doesn't shutdown, instead freezes on boot screen Plymouth)

I had force shutdown by powering off the machine.

This is not happening all the times.

I have been using Ubuntu for 6 months and never experienced this kind of problem.

I faced the same issue after I installed Ubuntu 12.04 on a newly built machine. This answer on another post helped me resolve it:

I resolved by adding acpi=noirq to the kernel arguments

sudo editor /etc/default/grub

Add

GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet splash"

Then

sudo update-grub
