Geeze! We should have noticed that it was "hibernation". Yeah, that writes the entire RAM out to swap. Insufficient swap will sure cause hibernation to not work.
It doesn't write the entire RAM, just what's in use, but I get it.
However I added a large swap file to bring the total up to 16GB and it *still* fails in the same way. And no, I'm not using more than 16GB of virtual memory:
$ free total used free shared buff/cache available Mem: 16361232 9910132 645876 497680 5805224 5503832 Swap: 16588792 3653100 12935692
The plot thickens.
It turns out that hibernation can't used multiple swap areas, so the only solution is to have a large enough swap partition to start with.

Might consider running a watchdog process on either chrome OR your swap file, which could throw an error if mem_in_use < mem_needed_for_hibernate
