Sorry for remaining quiet for so long. I have been looking into some very simple aspects (Config ROM parameters; the various existing firewire-sbp2 quirks that you already checked without success IIRC, and things like that). I didn't learn anything useful so far, unfortunately. I have been planning to check some more points, notably: - Does the PowerLook perhaps expect ORB addresses to be aligned at more even addresses, e.g. ORB size aligned? - Does it perhaps require simple buffers instead of scatter-gather buffers? - Another option that I could pursue would be to log the packet traffic with VueScan on OS X (using a PCILynx card for packet capture), compare that with that of VueScan on Linux, and hopefully find some significant difference there. While the third option could be quite time-consuming, the first two would presumably involve just a moderate amount of kernel manipulation and testing. I am chronically short of spare time though... -- Stefan Richter -=====-====- -=-= -=--= http://arcgraph.de/sr/ |
