          ^^^^
Check the output of "mount" and/or your /etc/fstab for a device called
"none".  On my system, there is devpts which has device "none", so it
is possible this is busy, and can't be unmounted, and hence root is also
busy and can't be ro remounted.  Maybe also check /proc/mounts for "none".
