Public bug reported:
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:

AGN Network Connection [8086:4230] (rev 61)
