Yes, I have an 8265.  No clue what form-factor it uses.

The card has been working just fine for years.  The ONLY change is that I
upgraded from F29 to F33.  So it is absolutely, 99.99999% likely to be a
software/firmware issue.

I have not tried; This is my "production" (work) laptop.

You're right that I should look at the powersave.  The correlation with
screen blank is an interesting clue.  I'm honestly not at all sure where
to look for that, or even what to look for.   I do know that even though I
have the screensaver settings set to blank and lock the screen when the
cover closes, that does not happen when I have an exterior monitor plugged
in.  So I'm honestly not sure *which* screenblank source is firing.

Even more interesting is that, for a while, there was a 1 to 2-hour (to
the minute) frequency of the outages.  At least according to IRC
reconnects.

*sigh*
