Subject: hwcrypt issue with rt73usb

Hi
I use a USB WLAN Stick (model: TP-LINK TL-WN321G) with hostapd.
With kernel26-2.6.36 this setup is not working anymore.
The interface is up and if I try to connect with another client
WPA handshake also seems to work, but the IP configuration via DHCP fails.
After downgrading to kernel26-2.6.35 the connection works fine again.
On #linux-wireless it was suggested to test with nohwcrypt and indeed after
modprobe rt73usb nohwcrypt=1
the connection worked fine again under kernel26-2.6.36.
