That seems plausible, given that the problem affects undi/snp as well as 
the iPXE intelx driver.  Assuming that you are chainloading into 
intelx.pxe/intelx.efi, then the common code path would be the closing of 
the interface: the underlying undi/snp driver is possibly writing some 
register on close that prevents the subsequent reopen from working (e.g. 
by clearing the AUTOC register).
