This bug was fixed in the package os-prober - 1.23ubuntu1
--------------- os-prober (1.23ubuntu1) hardy; urgency=low
* If any umount fails, sleep for five seconds and try again, up to three times; it seems that occasionally desktop automounting systems grab the device at just the wrong time (LP: #210620).
