This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'. I'm unable to reproduce this with latest (Fedora-Rawhide-20170303.n.0). It pxe boots fine on a AMD Seattle system using firmware ROD1002C (In reply to Mark Salter from comment #2) > I'm unable to reproduce this with latest (Fedora-Rawhide-20170303.n.0). It > pxe boots fine on a AMD Seattle system using firmware ROD1002C Are you using the grub that ships with the latest image in the PXE config? I used grubaa64.efi from grub2-efi-2.02-0.38.fc26.aarch64.rpm. But you got me to thinking, so I grabbed the BOOTAA64.EFI and grubaa64.efi from the os/EFI directory and used those successfully also.

fix malformed tftp packets
After chatting with pwhalen about this, I was able to reproduce by moving the grub file to the top level tftp dir. I did a packet capture and saw corrupted tftp read requests. There appeared to be an extra byte between the filename and type fields in the read request. This turned out to be caused by a downstream patch:
0088-Normalize-slashes-in-tftp-paths.patch
This patch collapses contiguous slashes in a filename to a single slash in the tftp packet. But it still advanced the packet buffer pointer and len based on length of original name. Anyway, an easy fix. Patch atteched.
