Thanks for the reply, Adam. I actually tried the
verbose_logging="YES"
in my /boot/loader.conf file prior to posting but it still hangs
after
the CD-ROM line for some reason.
Hey, no problem, Jeff. To be frank, I just signed up for
Questions,
after Google Summer of Code, and yours is the first one I've answered.
Glad to see that I've started on the right foot though.
It appears the only way the machine will boot up properly is if I
hit 5
on the boot menu. This obviously doesn't make remote reboots very
"admin friendly"!
I know that I setup something like this once, because I needed it
to
always drop to command line. I can help you emulate what's in menu
option 5, in a loader.4th script. But you'll have to drop the pretty
menu, and logo... If you're willing let me know.
Thanks again for your reply!
Like I said, no problem. Thanks for your enthusiastic support.
Regards,

P.S.: It's still me, the same Adam. Just figured I should use my
FreeBSD From: address instead of fsl.

Hey, Adam. I unplugged the CD-ROM from the mainboard and the first
time
it came back up it booted up fine. However, I immediately rebooted and
it hung on the Timecounters tick every 1.000 msec. So, since this is
the line that displays before the acd0: CDROM <TEAC CD-ROM
CD-224E-N/3.AB> at ata0-master UDMA33 line, I wonder if it is hanging
on
whatever is *after* these in the boot process.
ata2-slave: pio=PIO3 wdma=UNSUPPORTED udma=UNSUPPORTED cable=40 wire
ata2-master: pio=PIO3 wdma=UNSUPPORTED udma=UNSUPPORTED cable=40 wire

device_attach: afd0 attach returned 6
acd1: setting PIO3 on SiI 0680 chip
acd1: <VIRTUALCDROM DRIVE/> CDROM drive at ata2 as slave
acd1: PIO3

Hm... afd0... just noticed this... I have never used ATA floppy
drives. Doesn't mean they're bad, but I wonder what would happen if
you disabled this device too?
Maybe the virtual devices is hosing it up. I know there is a virtual
floppy drive in here somewhere too... I can see it in the BIOS but I
can't figure out how to disable it.
Is your CPU hyperthreaded? You might want to go in the BIOS and try
turning that off too... (Hyperthreading on FreeBSD doesn't give you
that much extra in performance... And exposes a few potential hardware
issues.)
At this point, I'm kinda poking around in the dark as to what device
could be causing it. In these situations, I start with the
bare-minimum to boot it up, and keep adding devices until it fails...
then remove everything, and try adding the failing device first. (This
means physically removing cables and such. This screens for
interactions between devices, and devices that may fail.)

How long is it sitting and "hanging"? How long have you left it? I
have one machine that needs about 3 or 5 minutes after the copyright
line, to boot the kernel. Of course you may have stumbled upon a
timing bug too. If that's the case, we should try to find as much
information as possible, and pass this one up to the people who can
track it down. I can help you force the machine to boot as you
wanted... but there may be other issues. Hopefully someone can help
you more than just forcing it to boot in option "5" all the time.
