I tried to use 2.6.24 but I have the same error. It looks like this problem happens when I try to read something in my ML555 board (Virtex5 evaluation board), but if try to write everything works fine. I tried to change the settings about inbound/outbound PCI-E windows but I have the same problem. Have you got any suggestions? Thanks.
