Machine locks up, usually with kernel Comm: Xorg Tainted

A few days ago, I upgraded to 17.04. Since then, roughly once a day, my computer locks up. These crashes occur in two ways:

 * While actively using the machine, Xorg locks up a CPU.
 * I leave the computer idle overnight, and the display won't wake up to the lock screen.

Nothing responds at all; I can't switch to tty1 to reboot either--I have to manually kill the power. I found most of the relevant errors in my syslog; all but one say "Comm: Xorg Tainted".

So, is this a known issue? Xorg bug? Kernel bug? Are these even the same bug?

Let me know what other info I can provide!
