Hi Mark,
I still don't understand what the problems is very much. Could
you give me answers against the following questions?
(1) Did you try "echo 1 > /sys/bus/pci/slots/XXX/power"?
(XXX is the slot number to which your card had been inserted)
(2) If the answer against (1) is yes, did "echo 1 > ..." work?
(3) If the answer against (1) is no, could you try that?
(4) If the "echo 1 > ..." works, does it solve your problem?
(5) If the "echo 1 > ..." doesn't work, could you give me the
output of "cat /sys/bus/pci/slots/XXX/*"?
(6) I think your slot is surprise removable. Is it correct?
Thanks,
Kenji Kaneshige

One of three patches to fix PCIe Hotplug so that it works with ExpressCard slots
on Dell notebooks (and others?) in conjunction with modparam of pciehp_force=1.
Fix pciehp_probe() to deal with ExpressCard cards
that were inserted prior to the driver being loaded.
