In the EFI_RETURN_STATUS_EXTENDED_DATA structure from PI-1.7, there may be
padding between the DataHeader and ReturnStatus members. The
REPORT_STATUS_CODE_EX() macro starts populating the structure immediately
after DataHeader, therefore the source data must provide for the padding.
Extract the BmReportImageFailure() function from EfiBootManagerBoot(),
prepare a zero padding (if any) in a temporary
EFI_RETURN_STATUS_EXTENDED_DATA object, and fix the
REPORT_STATUS_CODE_EX() macro invocation.

Laszlo,
Thanks for quick fixing this issue.
To match the status code it reports, how about rename the function as
"BmReportLoadFailure"?
Another minor comments in below.

I prefer "ZeroMem (&ExtendedData, sizeof (ExtendedData))" instead of
introducing local variables such as PaddingStart/PaddingSize.
This makes code more good-looking:).
