firewaire can not attach

[Manfred Lotz]

Hi there,

Running FreeBSD 4.9 stable after running
      kldload firewire
I get the following errro messages:

fwohci0: <VIA VT6306> port 0xc800-0xc87f mem 0xea007000-0xea0077ff irq 3 at devi

fwohci0: probe_and_attach failed with err=6
device_probe_and_attach: fwohci0 attach returned 5


I have no idea what this error means. Could anybody help?
