Comment (by anevilyak):

 Replying to [comment:10 taos]:
 > Does this unloading/reloading issue only affect the ipw2100 driver, or
 will executing the script also result in a visit to KDL on systems with
 different hardware that need firmware installed (e.g. iprowifixxxx,
 ralinkwifi, etc)? Some of the other firmware files must be first
 downloaded (difficult if you don't have a working network connection after
 booting in safe mode). IIRC, ipw2100 is one of the few native non-BSD
 network drivers, could this explain a different behaviour when
 unloading/reloading (assuming the other drivers aren't affected)?

 Without more information it's difficult to ascertain if this is a bug in a
 specific driver, multiple drivers, or in the kernel's driver reloading
 functionality, so that one can't really be answered at this point.
 Furthermore, it'd only impact systems where the driver finds any supported
 hardware at all, since it otherwise wouldn't get as far as installing an
 interrupt handler.
