Can you try doing

dracut -H /boot/initramfs-<kernel version here>

??

The man page from dracut says that -H is for the "current host"
instead of a "generic host". Maybe the "generic host" configuration is
messing up something with su that your actual host configuration
needs.

I use -H. As I have ben saying, my initramfs it's pretty up in sync
with my normal system.

Regards.
