Could you try the attached - untested - patch? It seems - from looking at= =20 the linux driver - that we have to remind the firmware of the ESSID=20 before doing a directed scan. That explains why it would sometimes work=20 (whenever we are coming straight from iwi_config) and sometimes not. Let me know if that improves things for you.
