In my case, it hangs just after loading a loader.conf file. I've also verified that loading gzipped kernels/modules works on 7-CURRENT/i386. So it's either loader vs. pxeboot issue (unlikely, since pxeboot reuses the loader binary), or i386 vs. amd64 issue (unlikely as well as amd64 reuses the i386 boot code), or more likely because some changes were not MFCed. Perhaps this one:
