Is this printed by Etherboot or a hardware error? I notice that the
protocol handler allocates a buffer on the heap the size of the file.
Are you doing multiple allocations or something, like what Eric
suggests?  Maybe the master handover isn't correct? Put some debugging
statements there.

Another thing you can do is put some code to make a checksum of the
whole buffer before handing it off to osloader since it's effectively
one big block. Then you can compare this with the file checksum or
between machines.
