I've got two servers that should be configured identically. Running SuSE 11. Trying to install infiniband drivers supplied by Mellanox, which should be compatible. On server 1, everything seemed to install just fine. On server 2, the install says that it is successful, but when I try to load the ib_srp module I get a message saying that it is unsupported. Here's the mod info from the two servers:

I'm not sure why on server is using the /updates/drivers and the other is using /updates/kernel/drivers. The same procedure was used to install the Mellanox OFED package on both servers.
