Drew,
after changing it I still get:
fpa0: <Digital DEFPA PCI FDDI Controller> port 0x9000-0x907f mem
0x80950000-0x80
95ffff,0x80960000-0x8096007f irq 4 at device 11.0 on pci0
fatal kernel trap:
trap entry = 0x2 (memory management fault)

a1 = 0x1
a2 = 0x0

The code is now:
rid = PCI_CBMA;
/* memres = bus_alloc_resource(dev, SYS_RES_MEMORY, &rid, 0, ~0, 1,
RF_ACTIVE); */
memres = bus_alloc_resource(dev, SYS_RES_MEMORY, &rid, 0, ~0, 1,
RF_ACTIVE|PCI_RF_DENSE);
if (!memres)
goto bad;
sc->sc_if.if_name = "fpa";
Did I miss something?
