Best bet for usb3 is likely to file an upstream kernel bug and work with the author. It will likely need someone to bisect where it failed using the upstream kernels and processes.

HI Dennis,

I've now got the system booting from the eMMC card.

Thanks again for the tip.  I noticed earlier as well that the mmc_block 
module was not being loaded.  I tried adding the mmc_block and 
pwrseq_emmc  modules as kernel parameters on the append line of the 
extlinux.conf file but that failed.  Rebuilding them into the initramfs 
image was the key and works but only if one updates the UUID information 
for the devices in both extlinux.conf and /etc/fstab.

I am currently in process of performing a "dnf update", to update to the 
latest release information.

BTW, any new thoughts on getting the USB 3 Hub to recognize devices?

Kind regards,
     Stewart

All, I have been working toward getting the Odroid-Xu4 to boot from the eMMC card but the system continues to fail in the same place no matter what I try. It dumps me into the dracut shell when it cannot find the root partition. I suspect one or more modules are not being loaded when booting from the eMMC. Following is my serial console output along with some output from the dracut shell. Does anyone have any ideas of what to try next?
you will need to rebuild the initrd pwrseq_emmc driver is missing from the initrd for it to boot simplest would be in a odroid-xu4 running from microsd mount /dev/mmcblk1p4 /mnt/ [ 192.561457] EXT4-fs (mmcblk1p4): mounted filesystem with ordered data mode.
