Scott, Neils,
Yeah, my understanding is as well that the orion_nand module is
causing these troubles. I do not know if the DreamPlug has a NAND or
not, but loading the module is surely optional.
You can try to do the following steps:
1. add the following "kernel" parameter (it's actually dracut acting
on it): rd.driver.blacklist=orion_nand
2. create a file in /etc/modprobe.d/disable-orion_nand.conf with the
contents "blacklist orion_nand"
This should prevent the orion_nand module from getting loaded and
hopefully your DreamPlugs boot a little further.
