Weird; I do get the correct hash:
    linux-firmware-44d4fca9922a252a0bd81f6307bcc072a78da54a.tar.gz: OK (sha256: b279ca4d086887c2efab13e28a7ca36e409410d3df38a62d7c7b5799ee3de916)

In the past, this could have been caused by a too-olld or too-recent tar
version. But nowadays, we do build our own tar when we need it. Can you
check what tar Fedora 28 has, and check whether Buildroot built host-tar
or not?
