Sure can! And in the mean time, I had figured out how to get debugging 
info out of gPXE (git tip), so I'm attaching that in case it's of any 
use (there's some extra debug output in that log that I attached in case 
something doesn't look familiar). I'll do the same with iPXE later on 
tonight. Looks like we're failing to get the capacity of the iscsi 
target, but as to why I have no idea. Any thoughts or ideas for more 
debugging would be appreciated.
