I tried a little more and captured the following Oops when I unplugged the 
cardd (note: This oops did not happen without your patch, I was able to 
insert another card and it worked):

Here's /proc/interrupts from right before the Oops:

Shortly after removing the card, I get a freeze, kernel panic with blinking 
LEDs. Can that be caused by your patch? I don't really understand what it 
does, but it seems to at least have any effect. What more can I do to get 
useful information out of it? 

Thanks,

sebas
