The issue seems arises when the laptop is booted after few hours of being s= hut down and it's related to the performance issue I cited; I need to reboot the machine twice (!) to get nice performance and not getting the error. I have put three firmware reset in a row in the if_rtwn.c and doubled the w= ait time before accessing to the registry after the reset and now the card is usable after a fresh boot. I'll test if it is sufficient to keep the wait state longer in the next day= s or it needs a "triple" firmware reset.
