FWIW, 0xC means RETURN_NO_MEDIA. Which is kind of strange.
But it is the first load which is done by syslinux.efi, not
by ipxe rom.
I vaguely remember it happens when syslinux.efi thinks it is reading a
disk and not booting from the network so it's most likely caused by one of
the bugs Laszlo has mentioned. I think I got this first with e1000 without
appropriate rom but this went away with virtio-net and disabling rom
loading by specifying empty value as suggested by Laszlo. But I could be
wrong, I don't remember it clearly.

Here's the original thread:
http://sourceforge.net/p/edk2/mailman/message/33735116/
It starts with the message explaining how it gets to the wrong path which
gets this message and replies from Laszlo about what causes this.
