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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHdpjYz62J6PPcoOkRAlChAJ9n7LY7AESihXhBZ01FnZL/e1ZrXQCfZJR1 NjcCDKTU+eT0ES46T2SZMRQ= =p/bh -----END PGP SIGNATURE-----
