just upgraded to 8.04 Beta. I see all the networks, but when I try to connect to any of them, NetworkManager hangs with the cpu on 100%, I can only kill it. I am using b43 firmware, so I am not sure it's relevant for this bug report.

P.S. It's the same no matter if there is encryption or not on the wireless network.

This is what syslog says:
