Problem Description:

I have tried 2.6.25-rc2 and there is causes wpa_supplicant to fails and freeze the computer when it is started. I am using WPA-PSK with CCMP encryption. A git-bisect run shows that the first bad commit is the following:

45b503548210fe6f23e92b856421c2a3f05fd034 is first bad commit

    [RTNETLINK]: Send a single notification on device state changes.
    
    In do_setlink() a single notification is sent at the end of the
    function if any modification occured. If the address has been changed,
    another notification is sent.
    
    Both of them is required because originally only the NETDEV_CHANGEADDR
    notification was sent and although device state change implies address
    change, some programs may expect the original notification. It remains
    for compatibity.
    
    If set_operstate() is called from do_setlink(), it doesn't send a
    notification, only if it is called from rtnl_create_link() as earlier.

If I revert it, wpa_supplicant works correctly. 


Steps to reproduce: boot gentoo and wait for net.wlan0 to start. When wpa_supplicant is called, it blocks the computer
