The "Try to free Memory with Signature" message must be coming from EFI (since 
that text doesn't appear anywhere in iPXE).

Could you try the attached patch, which will add debug messages to print out 
the address of each initialisation and startup function as it is called?

Please send the output from running the patched version of iPXE, and also the 
contents of bin/ipxe.lkrn.tmp.map (which will contain the symbol map needed to 
map the addresses back to function names).
