Okay, so the problem is not due to an active LVM partition.  Some 
testing has shown me that the patches to reenable BLKPG ioctls actually 
fix the problem of editing other unmounted partitions on a device with 
an active LVM partition.

Was the command in your testing actually the following or was there a typo?

$ sudo ./parted -s $dev u B mkpart F13-root $s2 $e2


If this was the command then what is a partition type of "F13-root"?
