did not crash for a day which does not prove much yet. I have now added a printk
that would alert me that the bugfix actually did anything and so far waiting to 
see it.

Something is still going very wrong with the automatic rate selection on the rt73usb
device - it is receiving fine with 11-24M but TX rate is not even 1M (50-100Kb/s). 
TX is fine with fixed rates 11-24M.
