Install FreeBSD 6.2 with usb cd-rom causes looping in BTX loader. I tried FreeBSD 5.5 and it still happened. Many people had the same problem and posted in web, but no response. Please look at http://lists.freebsd.org/pipermail/freebsd-stable/2005-November/019334.html for more  details.
>How-To-Repeat:
Find a machine with usb cd-rom boot support. Put disc1 in usb cdrom and boot. Kernel panic occurred.
