Description: Ubuntu Zesty Zapus (development branch)
Release: 17.04
What was expected to happen?
I expected the laptop would suspend after selecting 'suspend' from the shutdown dialog.
What happened instead?
The screen went black and I was logged out, but the laptop did not suspend. Looking at dmesg, I found the following errors:

As a work around, I found if I disable UWB (USB Wireless Bluetooth?) in the BIOS under Wireless, then the laptop will suspend when suspend is selected.
