SMP + 0.0.1 = hard lockup
UP + 0.0.2 not hanging so far.

I did in anothe posting but will repeat:

SMP + 0.0.1 : packet lost, card reset, card reset (exactly 2), frozen linux.
SMP + 0.0.2 : packet lost, card reset ad infinitum. never comes back...

will try that, but so far I think its 2 bugs: one is a bug present in
both 0.0.1 and 0.0.2 that in a SMP machine looses the card, and a bug that
was present in 0.0.1 and its not present in 0.0.2 that freezes the box after
bug 1 loses it. 

The second bug looks like the WDS reconect bug mentioned in the Changelog.

So far, UP + anyversion has no hangups...
