FYI, I've found an issue with the current kernel 5.6.x (maybe earlier)
the as3722_regulator module isn't added by dracut in hostonly mode (it
is added as all others regulators)
I need to add this:
add_drivers+=" as3722-regulator "
This prevents the board to mount the rootfs in mmc or sda when the
initramfs is in host-only mode.
I've reported the issue to dracut upstream at
Now I wonder if other boards are affected by such regulators tweak and
if a common solution can be found ?
Thanks for your advice.
