Having problem with a sever which has 18 PCI slots to run 18 PCMC IA cards

I think David Hinds is right. Those slots are on different PCI bus. I run the P series diag on those slots and also cardbus and seems like, the PCI to PCMCIA adapter which has PCI bus 2 is able to see PCMCIA card and any other PCI bus is not able to see PCMCIA card. But issue here is that the Linux operating system do see those PCI to PCMCIA adapters even though  they are on different PCI bus. Is there any place i can make some configuration modification so that i will be able to route PCI to PCMCIA on different PCI bus?
Anybody had test multiple P222 PCI to PCMCIA adapters on one systems before? If yes then how many maximum? Any suggestion or advice to look for a server which has multiple PCI slots which can support multiple PCI to PCMCIA adapters?
Please let me know if you need more information.

Bus mastering would only be required for a subset of CardBus cards to
be used; all cards can be detected and identified without it.

More likely, it is a bus bridging issue (those slots are probably on a
different PCI bus) and/or a resource management issue.
