 Belay that.  The hang definitely has at least _something_ to do with the
 ath driver.
 
 After seeing the hang while running the nv X11 driver (thereby
 eliminating the nvidia driver from suspicion), I spent today trying to
 narrow things down.  Again.  I'm now convinced that there's a problem
 with the ath driver, somewhere somehow.
 
 The hangs have happened very reliably when I'm some feet away from the
 access point in my living room.  This is a _very_ RF-noisy environment,
 with various and sundry equipment in all directions, cell sites nearby
 and no fewer than four other wireless networks in range.  In my lab the
 access point is less than six feet from the laptop, so I attenuated the
 signal by the expedient step of putting the AP in two nested antistatic
 bags.  It lowered the effective power (as reported by the "wireless
 network" Gnome applet) from roughly 50% to around 25%.
 
 I set the laptop up in my lab connected to a firewire console and I
 turned on as much debugging as I could find and could stand to watch
 scroll by.  In the end, I had dev.ath.0.debug set to 0x00ff0ff0.  I
 watched it happily spit out messages from the amrr rate module for hours
 while I used the network.  It turns out that I was accidentally using
 the fwe0 network, which I had forgotten I had set up.  It had gotten the
 default route.
 
 So I switched the default route to the wireless network, ath0, started a
 flood-ping to a local host and continued to browse the web.  Within a
 matter of just a very few minutes (like, less than five, probably less
 than three), I had the hang.
 
 I noticed that when I started the flood ping the rate-control algorithm
 started going nuts.  It changed the rate every time through the loop,
 every half-second.
 
 What follows is console output beginning shortly before I changed the
 default route.  It shows the driver going through several iterations of
 rate changes before the system locks.
 
 If this helps diagnose this a bit, please let me know.  Otherwise, at
 least give me some idea of what further information I can provide or
 further testing I can perform.  I'll be busy with my day job through
 the rest of the week, but I'll undoubtedly be back to trying to diagnose
 this hang next weekend.  I plan to leave my laptop in the diagnostic
 lashup, though, so it should be easy to do further testing.
 
 Console output follows, with a few comments interspersed.
