A panic a day

All,

I updated my kernel/world/all ports on Sept 19 2022.
Since then, I have had daily panics and hard lock-up
(no panic, keyboard, mouse, network, ...).  The one
panic I did witness sent text scolling off the screen.
There is no dump, or at least, I haven't figured out
a way to get a dump.

Using ports/graphics/tesseract and then hand editing 
the OCR result, the last visible portions is
