I created an F30 Live USB stick, but it won't boot properly. What happens is that it drops into emergency mode (dracut). Prior to this, journal messages from dracut-initqueue appear on the screen, the same message repeating every few seconds for a minute or so, then  it drops into emergency mode. The repeating message is:

dracut--initqueue timeout -- starting timeout scripts

Then it just says "Warning: could not boot" and drops into emergency mode.

I did verify that my download of "Fedora-Workstation-Live-x86_64-30-1.2.iso" is good (the calculated sha256sum matches the checksum from the download site). I created the stick using "unetbootin" which has always worked for me with previous Fedora releases. I tried rerunning "unetbootin" to recreate the on-stick OS, but the result was the same. I tried the stick on a Dell laptop and on a desktop based on the ASUS Z87 motherboard, same result. 

Anybody else seen this? Has anyone successfully created an F30 Live USB stick?

Thanks,
