It seems that iPXE didn't initialize Scope, so the value was assigned

After applying this patch, the crash never happened again.
Awesome! Can you please send this patch to ipxe-devel? (Although I can
see Michael is on the address list anyway -- good!)
Got it; thank you!
Will check the related code; it may make sense to have efi_ifr_op()
always zero the whole of the newly allocated space first.
Thanks again!
Michael
