2.5.74-bk5 + IEEE1394: ohci1394 doesn't work.

[Rui Saraiva]

I can't get FireWire/IEEE1394 working on kernel 2.5 (on 2.4 works fine).

When I load ohci1394 module, I get:

ohci1394: $Rev: 986 $ Ben Collins <bcollins@debian.org>
ohci1394_0: OHCI-1394 1.1 (PCI): IRQ=[5]  MMIO=[e4800000-e48007ff]  Max Packet=[2048]

ieee1394: unsolicited response packet received - np
ieee1394: contents: ffc00560 ffc00000 00000000 e4cd0404

And /proc/bus/ieee1394/ is empty.

If you need more info (kernel .config, /proc output, etc), just ask.

There's another problem when I unload the ohci1394 module:
