I've seen in a post from January that someone already had this problem  
but couldn't reproduce it.
I can't reliably reproduce, but I see this more often than I like.  
When this happens, it usually doesn't help to reload the kernel  
module. Sometimes it helps to use the rfkill switch though.

Here's a log with debug=0x43fff:

Feb  6 21:32:20 tank kernel: [11142.667719] iwlagn 0000:0c:00.0:  
Microcode SW error detected.  Restarting 0x2000000.
Feb  6 21:32:20 tank kernel: [11142.725640] Registered led device:  
iwl-phy0::radio
Feb  6 21:32:20 tank kernel: [11142.725789] Registered led device:  
iwl-phy0::assoc
Feb  6 21:32:20 tank kernel: [11142.725840] Registered led device:  
iwl-phy0::RX
Feb  6 21:32:20 tank kernel: [11142.725876] Registered led device:  
iwl-phy0::TX

That's unfortunately not more than without debug.

Here are follow-up retries from the module to restart itself:

This happens every 10 minutes.
