1394 gap count not updated by host pc

  1. The problem I see is that when their was a bus reset on the network
    each of the 7 connected nodes to the network has a gap count of 63.
    Also the host pc ( running Windows XP SP2 ) has a gap count of 63. Then
    a PhyConf package is send by the host setting the cap count to 24,
    followed by 2 bus resets. After this all the 7 nodes have a gap count
    of 24. Except for the host, it still has 63 as gap count.

    After this the host again sends a PhyConf package setting the gap count
    to 24 again. with the same result. Sometimes this keeps on going,
    sometimes it stabilizes after a few tries, in that case the gap count
    on the host is also 24 and the network operates just fine.

    What can i do to prevent this problem? under SP1 and Windows 2000 i
    don't have this problem because the host will not send the PhyConf
    package to change the gap count. Is it possible to disable this feature
    in the 1394 driver?
