setting the variables, between verbose loading the verbose probing. I know
the difference in what prints, but I don't know how to set this up
permanently without getting me that verbose probing, which I would like to
avoid.

I have absolutely no idea what "verbose loading" and "verbose probing"
mean. All I know of is the boot_verbose loader variable, which enables
additional kernel messages. It does not affect the way the kernel is
loaded, or the way devices are probed.

I'm sorry, Dag, but I am myself having problem describing it. I have been
asking for names, but while I get some guesses about the loss of printing,
they haven't given me names to use. I see two items that I can get, when
booting. If I stick "-v" in /boot.config, then when the kernel probes, all
the probes are verbose. Stuff like my HDaudio card print incredibly
verbose listings. OK, that's what I will call here Print#1

The other thing is what I can see if I see the ascii-graphical loader (the
picture, in ascii-graphics, either of a BSDaemon, or of the letters
"FreeBSD", and a list of about 9 options for booting. If I select item #5,
then I get a listing. The listing is quite distinct from what I identify
as Print#1, so I'll call this Print#2. If I either hit return at that
ascii booting menu (to get the default) or select item #1, then when it
boots, I get no print at all: I see the very first spinner character (but
it never prints the second one), and the next thing I see, it's printing
"Login:". This Print#2 looks like the old non-verbose booting messages
that I used to see, before I lost the printing of all booting messages.

So, what do you call Print#1 and Print#2? Sure would help out, if folks
would answer these, and not only answer the real question, which is why my
ordinary non-verbose printing of booting messages went away. If you want,
I can tell you, referencing the "verbose loading", that's my Print#2 When
I talked about "verbose probing" I am talking about the Print#1. The
reason I grabbed those definitions (clearly in desperation) is because it
seems to me that Print#1 is called out as device probing is starting, and
Print#2 is called out before all loading has begun. Yes, I know that those
two times abut one another, and aren't particularly good names. BUT note
that when you supply a name, that one I guarantee I will stick with,
religiously, for now on.

I'm beginning, right now, to wonder: I increased the dmesg-buffer to 64K, I
wonder if maybe that might possibly cause the bug? I know it shouldn't,
but it wouldn't be the first time this week that I found weird behaviour in
the kernel: if you set the number of vtys from the default 16 down to 8,
that caused me to lose keyboard input to my X11. I got REALLY lucky to
find that one, but it's a testable fact.
