Problem Description: after inserting a pcmcia cardreader in the slot the
machine can't go to the suspend-to-ram mode.
Steps to reproduce: insert a pcmcia cardreader into the slot and do "sleep 2 &&
echo -n "mem" > /sys/power/state" (I use a script that doesn't removes the
pata_pcmcia module).

The output of dmesg after inserting the cardreader:
