Cool. I know what that's like.

Um, but, can you please look, just a little? :)

I do not mean "resolve the bug now kthx !!111", but perhaps judge
complexity/difficulty, or see if there is some key information or
testing that I could do while I have the unit?

The unit is currently taken out of production but needs to go back with
the workaround by next week or so, and I don't have a lab unit since this
is an uncommon hardware type in the fleet. I will still be able to do
limited testing with remote hands-and-eyes, but have much better
possibilities while the unit is still in the lab.
