A screenshot of a verbose boot is insufficient; as I'm sure you noticed
there are pages upon pages of information before the lock-up/crash.
Those pages are what folks are interested in.
Because the system is hung, I doubt hitting Scroll Lock + using
PageUp/PageDown to go through the kernel message scrollback will work.
You're going to need a serial-based console (i.e. hook something up to
COM1 on the motherboard, and get a null modem cable to connect to
another system where you use a serial port/terminal emulator (ex. PuTTY
for Windows, etc.) that has a scrollback buffer which you can copy-paste
or save. Set your serial port for 9600 baud, 8 bits, no parity, and 1
stop bit (9600bps, 8N1). You'll need to have physical access to both
systems simultaneously.
At the VGA console, boot FreeBSD then escape to the loader prompt
("ok") and issue the following commands:
set boot_multicons="YES"
set boot_serial="YES"
set console="comconsole,vidconsole"
boot
You should begin seeing output on the serial port, and the system will
eventually hang/etc.. Then provide the captured output from the serial
port here. :-)
