The debug message (just after the download "...ok" message) is : EFIIMAGE
0xb815d048 could not boot: Error 0x 7f048182
That's not a message which can be generated by iPXE:
$ git grep EFIIMAGE

I'm assuming the message was "EFIIMAGE 0xb815d048 could not load: Error
0x7f048182", since you said that it was generated from the "kernel"
command (rather than the "boot" command), and there should be only one
possible error message on that code path.
The error is EFI_INVALID_PARAMETER. It's plausible that the platform
firmware is complaining about our NULL parameter for DevicePath. Could
you try the attached patch, which provides a dummy empty device path?
Thanks,
Michael
