same result: the patch doesn't fix the problem. However after upgrding the Prism firmware (1.1.0 -> 1.1.1) the lock up stopped. Still I cannot get more that 2.5Mb/s Tx from the Prism (as a client) to another client (Aironet). A little better (3 / 3.5) from the Prism to the AP (DI 614+). "wi" is reporting a lot of TX collision, but "an" isn't when I change the direction of the traffic. In this case I get better rate.. but still not optimal as "wi" get conficts on the ACKs. Another anomaly shows up when running dhclient: often the system freezes/slows down for a few fractions of a second (BTW: I've noticed this with the Aironet driver as well). Also acquiring a lease has become more unreliable..
