We've been hit by this twice this week on two NFS/RDMA servers, so I'm glad to see this! But, for us it happens with memless ConnectX - our mthca devices are ok (but OTOH they're memfull not memfree) I'll be happy to test it with our misbehaving cards, but I can't do it until next week since they just went into a box for shipping. In the meantime, dare I ask - what's different about memfree cards that limits the sge attributes like this? And, what values result from the new code? The ConnectX ones I have report 32, and fail when trying to set that.
