[fedora-arm] couple of questions

I have a raspberry pi 3b+ and I have a few questions 1) I try to boot the Fedora 28 aarch64 raw image I run into an issue with the "Rx: failed to receive: -5".. I believe someone has a bug report opened already.. any idea on when this might be fixed? https://bugzilla.redhat.com/show_bug.cgi?id=1573261 I can only boot the armhfp release as of right now. I guess I'm just looking for more detail about this issue. 2) if I want to network boot and I can't use aarch64 because of the above issue what could I use for the boot file for armhfp? I'm familiar with booting x86 systems and you can typically use pxelinux.0 to start the process. If you could provide a download link that would be great on instructions on how to create the boot file would be fine. thanks, Mike
