This branch works better. I plugged and pulled some cards and so far it works
for me. Minor nit, compiling gave me:

  CC [M]  drivers/pcmcia/ds.o
  drivers/pcmcia/ds.c: In function ‘pcmcia_delayed_requery’:
  drivers/pcmcia/ds.c:720: warning: ignoring return value of ‘bus_rescan_devices’, declared with attribute warn_unused_result

I'd like to do some more testing, though.

Another thing: You said these locking patches were for 2.6.34. What about
waiting for 2.6.35, so your other patches can stabilize in mainline, and the
locking stuff gets another round of testing? I'd fear hunting possible
regressions ("My card/slots stopped working!") might get troublesome otherwise?

Regards (and thanks for this work!),
