Sorry for the delay; finally(!) had a chance to do this (inspired, in
part, by the recent update of x11/nvidia-driver).

So: I used "portmaster -o x11/nvidia-driver x11/nvidia-driver-390" to
replace the older driver with the current one.

This was while running:
FreeBSD g1-55.catwhisker.org 12.2-STABLE FreeBSD 12.2-STABLE #1138 stable/12-n233908-5c1c9f08d74: Fri Sep 24 03:32:01 PDT 2021     root_at_g1-55.catwhisker.org:/common/S1/obj/usr/src/amd64.amd64/sys/CANARY  amd64 1202508 1202508

with a ports tree at main-n559560-5bec538caeed (and all ports up-to-date).

The panic was reproduced.

I have not yet looked at that -- and, of course, I needed to re-replace
x11/nvidia-driver with x11/nvidia-driver-390 in order to have a
functioning laptop to be able to do any of that.

I will copy dumps &c. to

Peace,
david
