Problem with BCM4312 and EAP mode

[Arseny Klimovsky]

Hello, list

I'm using b43 driver on laptop Dell Latitude E4300. It works great at 
home with WPA-PSK mode, thank you!
But I cannot use it in a WPA-EAP mode.

The system log is full with such errors when I try to connect to the net:
Oct 24 11:32:26 odette-laptop kernel: [596357.880058] b43-phy0 ERROR: 
MAC suspend failed

It is Ubuntu 10.04.3 with new vanilla kernel
