           Summary: PCMCIA: socket *** DANGER *** unable to remove socket
                    power
    Kernel Version: 2.6.20.4
            Status: NEW
          Severity: high
             Owner: linux-pcmcia at lists.infradead.org
         Submitter: linuxuser at knabber.homelinux.net


Most recent kernel where this bug did *NOT* occur: I don't know any.
Distribution: Debian Etch
Hardware Environment: Thinkpad T41p
Software Environment: pccardctl eject
Problem Description: 

The command "pccardctl eject" gives the following warning:

kernel: PCMCIA: socket f793c428: *** DANGER *** unable to remove socket power

It seems that this warning is wrong, because the pcmcia-card is offline. (LED 
is off.)

Steps to reproduce:
Inserting a pcmcia-card (I use the merlin u740.) and after this use "pccardctl 
eject". If I remove the card without pccardctl eject I get no warning from the 
kernel.
