We have found that the nvidia/mellanox OFED installer disables the cifs kernel module and implements a dummy kernel module to disable cifs. In the release notes for OFED it was stated that they disabled the module an inserted a dummy module because OFED broke cifs and they wanted to prevent errors from being displayed.
It was also mentioned that the issue could be resolved by rebuilding the original cifs module.
They cannot however provide instructions on how to do this.
If anyone has run across this and/or has any advice it would be appreciated.
Thanks,
