To trigger this, I booted with a U.S. Robotics USR2210 Wifi card plugged into my cardbus slot. I then ran "pccardctl eject" and then removed and then reinserted the card. After looking at the latest PCMCIA info, it seems that I may need to add some kernel boot options to work around a BIOS or other problem that causes trouble when removing a card.
