Scary! :) The current code assumes that it can make modifications to the
STE in any order and enable translation after a sync. So far I haven't
been able to find anything that violates this rule in the spec: "If
software modifies the structure while it is valid, it must not allow the
structure to enter an invalid intermediate state." So maybe it's fine,
though to be safe I would have started with disabling the STE

Thanks,
