I will try that, but I'm not sure how soon -- I use this laptop whenever
I'm interacting with computers (which is most of the time that I'm
awake).  I will see what happens with the newer laptop later today.


FWIW, the copy of the laptop's "head" kernel config in
http://www.catwhisker.org/~david/FreeBSD/head/CANARY is current.

And the only difference between the stable/12 config and the head config
is:

g1-48(12.2-S)[3] diff -u FreeBSD-1{2,3}/CANARY
--- FreeBSD-12/CANARY   2019-07-08 10:43:51.940026000 -0700
+++ FreeBSD-13/CANARY   2015-03-22 10:03:41.000000000 -0700

 #
-# options      DIAGNOSTIC
+options        DIAGNOSTIC
 
 #
 # REGRESSION causes optional kernel interfaces necessary only for regression

Hmmm... so I suppose that re-disbling DIAGNOSTIC might be a reasonable
thing to try, as well, yeah...?  :-}

Peace,

There's no point in asking Trump "Sir, have you no decency?" -- it is
already well established that neither he nor his enablers have any.
