Description of problem: Booting Fedora-Minimal-28-20180407.n.0.aarch64.raw.xz on RaspberryPi-3B fails to load the kernel from uSDHC, and after a while begins attempting to boot over ethernet via PXE.
Version-Release number of selected component (if applicable):
How reproducible: every time (2 out of 2 so far)
Steps to Reproduce:
1.xzcat Fedora-Minimal-28-20180407.n.0.aarch64.raw.xz > /dev/sdX
2.boot via uSDHC on RaspberryPi-3B
Normal uboot prompts on VGA console (3 seconds), then about 22 seconds of rapid scrolling:
unexpected command 16 error
<<the above 2 lines appear 6 times total>>
** Can't read partition table on 0:0 **
<<the above 13 lines (6*2 + 1) are repeated rapidly many times>>
then at about 25 seconds elapsed from power-on, attempt to boot over the network using PXE.
Expected results: normal boot from uSDHC.
Additional info: 32-bit ARM does boot from uSDHC (Fedora-Minimal-armhfp-28-20180407.n.0-sda.raw.xz)
Fedora-Minimal-28-20180410.n.1.aarch64.raw.xz still fails the same way.
Fedora-Minimal-28-20180415.n.0.aarch64.raw.xz gets beyond this stage. The uboot "select a kernel" line appears and is selected automatically after a few seconds. VGA console text begins to scroll after another 1/2 minute or so, then after several more seconds video sync is not detected, similar to bug #1563421 on 32-bit ARM. I Close this bug because the symptom went away.
