Description of problem:

Rawhide -- upgraded from F10
NetworkManager used to manage connections
After suspend/resume iwl3945 driver does not work.

Observed network interface "wlan0" was not up:
wlan0     Link encap:Ethernet  HWaddr 00:13:02:29:D1:81  
          BROADCAST MULTICAST  MTU:1500  Metric:1

Trying to "up" resulted in

SIOCSIFFLAGS: Connection timed out

In dmesg observe errors like
iwl3945 0000:03:00.0: PCI INT A disabled

I then used "rmmod iwl3945;modprobe iwl3945", and interface came up fine, networkmanager kicked in & back on-line.

Seems to happen regularly, did not happen with F10
