Ok.  I updated just the one file since it appeared like one of the few  
changed files

	/usr/src/sys/boot/i386/libi386/biosdisk.c

and rebuilt things with

	cd /usr/src/sys/boot; make cleandir obj depend all install

and it was okay.  No problems.

Then I did sync'd all of the changed files for /usr/src/sys/boot and  
my machine is hung again at boot, so we have narrowed it down to  
somewhere in /usr/src/sys/boot/.

Time to reinstall from a DVD and try it with finer granularity.  This  
will take some time.

There appears to be only four files that have changed in /usr/src/sys/ 
boot from June 8th (all working fine) to June 11th (dead in the  
water).  They are:

/usr/src/sys/boot/Makefile
/usr/src/sys/boot/i386/Makefile
/usr/src/sys/boot/i386/libi386/biosdisk.c
/usr/src/sys/boot/i386/loader/Makefile

I have ruled out bisodisk.c, as stated above.

That means that the Makefiles are building new stuff that previously  
was not built, namely

	zfsboot gptzfsboot

I believe it has to do with that.  More help is needed!  I am tired of  
reinstalling the OS, but I am much more paranoid about updating my  
other machine in any way now, as it could erase that whole machine.  I  
can't believe I am the only one seeing this...
