Ubuntu 16.04 laptop hanging, requires powercycle

I'm seeing a weird situation where my new Dell Inspiron laptop running Ubuntu 16.04 is unpredictably hanging, and I can't seem to figure out why. I haven't observed any consistent behaviour that causes it. What happens is the windowing system (using Gnome) freezes, no mouse action, no response from keyboard, can't drop to shell, etc... so I have no choice but to do a hard powercycle to bring it back up.

When I look through the syslog for possible problems, sometimes I see waings, but those waings also occur when the machine is NOT then locking up. See below for the section from my syslog for the time immediately preceding the most recent time this has happened.

I am an experienced sysadmin, but new to running ubuntu on a laptop, and this problem is frustrating my attempts to figure out what's going wrong.

I'm hoping someone can help me track down what the hell is going wrong.

Thanks!
