I attempted to get a bisect going but failed. These commit logs look promising though as to where the fix lies.

Looking in kern.log I see this output, scrolling on repeat, until I long-press the power button to shut off the laptop. Happened occasionally in Ubuntu 19.10, now regularly on 20.04. Persisted with the nvidia proprietary driver as well as the open source one. It has persisted across several official ubuntu packaged kernel revisions. I got kernel taint down to "0" and it kept happening. (Previously virtualbox and nvidia driver were in there.)
