using a cardbus based system with pccbb providing the pcic interface). Something isn't quite right.. when the driver allocates and activates its resources, the IO space that was requested reads as all zeros (versus the original 0xff's as it normally is when there is no device responding). Also, deactivate the resources before releasing them. OLDCARD doesn't seem to care but NEWCARD/CARDBUS get rather unhappy if you release a resource that hasn't been deactivated yet. Make pcic_p.c only compile with oldcard kernels.
