This is really an annoying message and it dumps a bunch of garbage as the system is booting up. Caused me a lot of confusion in getting my flash file system set up and working. My command line arguments first set up the "physmap-flash.0" then something else tries again. I also seem to have redundant physmap-flash entries in the /sys file system.
I do have flash working but this message will not go away and I've not been able to find it's source. Any help or suggestions would be MUCH APPRECIATED.
