What is weird is that the following happens: Have the Nokia modem card in slot 0 suspend resume (sometimes) it gives: sio1: test 3 failes remove the card resinsert it sio1: test 3 fails remove the card insert another modem card, for the same irq see that there is no free config So somehow pccardd also thinks that the first modem card is still present although it's not. So apparently, the unregistering of the card during suspend did not work. Let me check my logs....
