And why did you complain on systemd not displaying something if the problem is completely unrelated to systemd (it could be a kernel/udev issue)? Now I agree that something is really wrong if you can't at least get a text login console, but again if it's a kernel hand, systemd can't magically bring something on the screen.
I don't say that it impossible that systemd is in fine the cause of your problem and that fix is needed to solve your case. But without more information is't both impossible to clearly prove that's a systemd bug, and impossible to create a fix if it's the case.
I never say to report directly to systemd project. Please report first to the Fedora community.
I don't know Fedora, but on Debian you can install sysvinit or upstart as a systemd alternative to help testing if the bug also show without systemd.
