I'd done a kernel update -- on a booted SD card image -- and on reboot
it did the same... Scrolling temp warning and notice of shutdown (but
apparently spending so much time handling the temp warning it wouldn't
actually shutdown; had to pull the power).

Had to reimage the SD card, but wasn't getting warnings from that
"stock" image. Didn't measure temps (I do have an old Ryobi IR
thermometer). I did notice the card edges were rather heated when I shut it
down and picked it up.
apt-get update/upgrade alone didn't cause the situation, seems to be
something in the kernel update -- a change in thresholds? Or some
calibration flaw?
I do think I should locate some fan that can mount on it (and here I
though an R-Pi 3B in a case was running warm -- my Pi-Star node typically
registers 50-53degC, and that is "amber" on the status page.
