I can certainly try that (probably tomorrow), but I'd like to add
that I didn't just add DIAGNOSTIC when I updated the kernel; that
option was in force on my 5.0.1 kernel and did not cause a problem.
I'm concerned that just turning off DIAGNOSTIC will simply mask a
problem; I hope that the bug can actually be found and squashed.
But thanks for the workaround; it should allow me to run with
the "2010-003" security advisory addressed, which is good.

Weird. I wonder if it's some kind of clue that the oddities I saw
happened with the *old* kernel, but booted by name "/netbsd.old";
I'm somewhat ignorant of how this works, but could something be
being picked up from "/netbsd" (the new kernel) even when this is
not the booted kernel?
That reminds me to report, though I doubt it's relevant: I did make
one change to /etc/sysctl.conf back in January:
