Hi, I have a 64-bit pci card which requires a pci-x slot to operate properly. When I place the card into a 64-bit PCI-66 slot (not pci-x, 3.3v only), the driver's probe function crashes the kernel when it attempts to call pci_read_config_dword. The card manufacturer says that only use in pci-x (64-bit pc98/c24, both 5v and 3.3v) slots is supported. Is there anything I can call from within the probe function to determine the type of PCI slot, so I can return an error before calling pci_read_config_dword and thus avoid crashing the kernel ?
