I just installed the infiniband-backport-2.6.12-to-2.6.9-kernel-fixups-01.diff infiniband-backport-2.6.12-to-2.6.9-openib-drivers-02.diff infiniband-backport-2.6.12-to-2.6.9-openib-fixups-03.diff backport patches on a couple of old 900Mhz IA32 Xeon boxes and was able to build the kernel, load IPoIB and ping another node. I used the Redhat configuration file /boot/config-2.6.9-5.ELsmp, did a make oldconfig and selected modules for all of the infiniband drivers. Then I built and installed the kernel with no problems. Maybe it is the platform (I have seen problems in the past with the BIOS on some platforms being able to map the Mellanox H/W correctly) or could bad Mellanox H/W cause this ? Do you have any other platforms that you could try it on ? woody _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
