Rummaging through my old messages* shows I'd never tried wi on 8.0 
through 8.1-stable, nor apparently 7.x, though I used to use it 
infrequently but successfully on 4.8-R, 5.5-S and 6.1-R.

I can confirm Peter's report for my Cabletron Roamabout (Wavelan clone) 
on 8.2-R, now:

With nothing to talk to here, I didn't try configuring wlan0 further.

wi0: detached

One earlier attempt on 8.2 shows the same interrupt storm on insertion, 
except on an immediately subsequent insertion, it picked on irq 5 - ah, 
but that was trying it in the other slot.  On that occasion I didn't 
bother trying to configure wlan0.

Could be, but I vaguely recall a few other threads saying wi was broken?

cheers, Ian
