Bug Description
Occasionally, my wireless interface stops working, with the following message in the log:
Mar 10 09:30:45 perseus kernel: [37783.753286] iwl4965: Microcode SW error detected. Restarting 0x2000000.
When this happens, the interface stops passing traffic, and I'm unable to associate with any networks. Unloading and reloading the module is the only thing which gets it working again. This is on a ThinkPad T61 with a hardware kill switch and the following wireless device:

In my case, network manager didn't know the connection down, but when I told it to reconnect to my SSID, it was able to, without having to go through to cycle the driver with modprobe.
