Something is strange in ovirt-engine repository.
Look at, you may notice that it is mered without verify and +2, and that last rebase which produced Patch set 6, committed Patch Set 5 (2nd time).
The look at, this change depends on it-self, although it is in review state (as in submitted once) it is already merged into repo, so rebase only make it rebase upon it-self...
Abandon  does not help, as every patch that is rebased to HEAD will be rebased on top of it... causing it to be submit pending.
I am not sure what is the best solution for this, maybe to use force push to remove these last two changes? Or change in the database the status of the last?
