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

it should then boot. I plugged in the emmc from my pinebook to see if
it worked. u-boot is not loading from it but its otherwise working okay
