Full system freeze: kernel BUG at /build/linux-7LGLH_/linux-4.10.0/include/linux/swapops.h:129!

Installed Ubuntu 17.04 beta, was logged in to Mate, had Chromium, Thunderbird, and a terminal with Vim running.
I was switching back and forth between Vim and the browser when the whole system just froze.
The desktop didn't react to mouse/keyboard, not even to Ctrl+Alt+F1..Ctrl+Alt+F7.
It did react to SysRQ though: alt+printscreen+s, alt+printscreen+u, alt+printscreen+b, alt+printscreen+b.

Upon reboot I've seen this kernel error in /var/log/kern.log (see attachment for full details):
