Hi Erik,

Thanks for getting back to me.  The original problem is the same
issue...we are still working it, but we've isolated the configuration
where the issue manifests itself.  It has to do with the FreeBSD
pxeboot and Brocade switches.  We will continue troubleshooting in our
lab.  When we've identified a fix/workaround I will be sure to follow
up here.

I can't speak to all the technical nuiances you reference here but I have a diskless
booting system which runs 8.2-STABLE and it's been running flawless for several
months. I last did make buildworld on the server's os and the diskless's boot
partition in December...all is well for me.
