Cardbus not detected by PCI / hotplug


Hi,

I'm having trouble with cardbus - when I insert a cardbus card in the PCMCIA slot in my board the card services driver recognize the insertion but nothing else happens other than these lines which appear in the kernel log (debug mode):

Jan 1 00:16:26 machina kernel: cs: pcmcia_socket0: parse_events: events 00000080
Jan 1 00:16:26 machina kernel: cs: pcmcia_socket0: insert
Jan 1 00:16:26 machina kernel: cs: pcmcia_socket0: setup
Jan 1 00:16:27 machina kernel: cs: pcmcia_socket0: reset
Jan 1 00:16:27 machina kernel: cs: pcmcia_socket0: insert done
Jan 1 00:16:27 machina kernel: cs: pcmcia_socket0: send_event(event 4, pri 0)


The device does not appear in `lscpi -v`.

Activating the hotplug subsystem (/etc/init.d/hotplug start) does no good either and doesn't load the pci-hotplug.ko module at all - when I try to manually load pci-hotplug.ko using modprobe, it says something about a bad agent.

When I plug the card out I get this message :

Jan 1 00:21:02 machina kernel: PCMCIA: socket 83603830: *** DANGER *** unable to remove socket power



Kernel version is kinda old - 2.6.10, but upgrading is impossible at the moment.



Any ideas what's wrong?
