Subject: iwl3945 Microcode SW error, and then can't stop Rx DMA

After a while of running on my iwl3945 I get the following error:

[ 8414.072734] wlan0: CTS protection disabled (BSSID=00:13:c4:f4:25:30)
[ 8473.409534] wlan0: CTS protection enabled (BSSID=00:13:c4:f4:25:30)
[12059.081930] iwl3945: Microcode SW error detected. Restarting 0x82000008.
[12059.081950] iwl3945: Error Reply type 0x00000005 cmd REPLY_TX
(0x1C) seq 0x0000 ser 0x0000004B
[12060.076397] iwl3945: Can't stop Rx DMA.

I then have to remove the module and add it back. Haven't been able to
replicate it again, but will let you know once I do see it again. This
is running the latest pull from wireless-testing.git.

If you can reproduce it, please have the driver loaded with debugging
(debug=0x43fff). This will cause the microcode event log to be dumped to
the screen and we can then pinpoint what caused the microcode to
complain.
