This crash may be more general that the zd1211rw. I am also getting kernel 
panics in __netif_schedule with b43legacy for kernels 3.4.0 and 3.5-rc3 from 
wireless-testing. On this box, an RTL8187B works fine.

As reported here, the connection is OK until a heavy load is started. In my 
case, it was a package update command for my openSUSE distro.

Is there a possibility that this is still related to the single output queue 
problem, or does the zd1211rw have multiple queues?
