If it's similar I could work on it myself. I actually installed 4.8-RELEASE last night, and did a tweak of fwohci_pci_probe to accept the chip. It then told me to set PNP_OS=NO in the BIOS, which I did. After that, it seemed to detect the interface: fwohci0: <SONY CXD1947> mem 0xfecffc00-0xfecffdff irq 9 at device 9.0 on pci0 fwohci0: PCI bus latency is 64. fwohci0: OHCI version 0.0 (ROM=0) fwohci0: No. of Isochronous channel is 0. fwohci0: EUI64 00:00:00:00:00:00:00:00 fwohci0: fwphy_rddata: loop=100, retry=101 fwohci0: Phy 1394 only S100, 0 ports. fwohci0: fwphy_rddata: loop=100, retry=101 fwohci0: Link S100, max_rec 2 bytes. fwohci0: max_rec 2 -> 512 firewire0: <IEEE1394(FireWire) bus> on fwohci0 sbp0: <SBP2/SCSI over firewire> on firewire0 fwohci0: Initiate bus reset fwohci0: fwphy_rddata: loop=100, retry=101 fwohci0: fwphy_rddata: loop=100, retry=101 Hmm, looks like it failed to read anything back, and fwcontrol doesn't find anything either: # fwcontrol fwcontrol: open: Device not configured That's with no devices attached, but I imagine that the host controller itself should show up. So looks like a no go... Regards, Brian.
