while the card is inserted:

and after the card is removed:

So the only modules that get loaded are ohci_hcd and usbserial, of course the PCMCIA modules are also involved. I can do "rmmod ohci_hcd" without problems. I can also do /etc/init.d/pcmcia stop without problems and it removes the yenta_socket and ds modules properly. At this stage, lsmod looks like:

Now doing /etc/init.d/hotplug stop hangs while stopping USB:
Stopping hotplug subsystem: input input [success] isapnp isapnp [success] net net [success] pci pci [success] usb
but I was under the assumption that is probably caused by the usbserial module. The process list shows indeed rmmod usbserial. But to make sure, here is the sysrq-t output:
