>Description:
	Doing an upgrade of FreeBSD from FreeBSD-BETA6 i
to FreeBSD-BETA7 the recommended way leaves my system completely unusuable due to a weird <biord> stuck
while doing "make installworld". After the system wrote several files it 
freezes. I can type something into the console, type Ctrl-T offers some 
messages about "install <biord> xxx xxx xxx" or similar.

I followed the steps recommended when upgrading: make buildworld, make kernel, reboot kernel in single user mode, make installworld.

I also realzied, that booting an alternative kernel (I saved my old kernel)
results in a stuck console (single user kernel, normal booted kernel, both beta 6 and beta 7 kernels).

After crashing and trashing my system two times and rebuild took three days I did a final experiment: installed BETA6 from disk (got a lot of BTX loader haltet,
but I realized this was due to some memory problems I never had before). Then did a cvsupdate to get the most recent BETA7 stuff, compiled a kernel,
booted this kernel in single user mode and did simply a 'find /'. After a few seconds the system froze at the same point as when doing a regular installworld.

I rebooted the the system into multiuser mode with the same kernel (BETA7)
with ACPI/SMP enabled and did a installworld the old way using the
/usr/src/installworld_old script. Everything got installed well!

My kernel config is a GENERIC config with several driver not used commented
out.
