I suspect the 7.0 stuff is a bug in the release media, but almost
certainly a red herring in this case.

This is really odd.  It sounds like you are somehow booting from one
root file system (with the 6.2 kernel) and then mounting another one
over the top of it.  I'm not sure quite how I'd go about tracking this
down.  A dmesg might help and the output lsdev in the loader might be
interesting.
