Any chance that the delays (or other parameters) depend
on the operating temperature(s) of some parts?

If yes, then some of the following about the Rock64 V2
context that I have access to might be relevant to
explaining my already reported V2 results (not much
for Retr):

A) The Rock64 has a "case" that is really just a top
   and a bottom with posts: open on all 4 sides.

B) It has a fan blowing down on the board from the
   top.

C) It has a heat sink on the SOC, which the fan blows
   on directly.

D) It has a heat sink on the RAM, which the fan also
   blows on directly.

(I've not dealt with a more modern non-debug kernel
build yet. It still may be some time before I deal
with that.)
