* -re0906.1

Got this traceback during an automated install test.  There was no lvm in this
install.  The previous install did not have lvm either (although it did have
root on /dev/md0 raid1).  The machine had run an lvm case earlier that day, but
afaict it had gone through about 9 successful installs of the same tree before
it hit this traceback.

Will attach details.
