The aic7xxx.c driver finds the PCI cards primarily based on the array:
struct
{
unsigned short vendor_id;
unsigned short device_id;
aha_chip_type chip_type;
aha_chip_class_type chip_class;
} const aic7xxx_pci_devices[] = {
{PCI_VENDOR_ID_ADAPTEC, PCI_DEVICE_ID_ADAPTEC_7871, AIC_7871,
AIC_787x},
{PCI_VENDOR_ID_ADAPTEC, PCI_DEVICE_ID_ADAPTEC_7850, AIC_7850,
AIC_785x},
..
The original driver has ascending numerical order which means that the
AU with 7861 gets recognized before UW with 7881. The example above is from
my system where I have modified the driver so that my AHA2940 connected to
the system disks gets recognized before the card connected to "secondary"
devices. You can move the line defining 7881 to the top of the array and
after remaking the kernel your problem should be solved.
