Hello Jack,
How was MOFED built? Are you using the MOFED or the upstream RDMA kernel
drivers? If you are using the MOFED RDMA kernel drivers you will have to
contact Mellanox. Otherwise I propose to try to reproduce this with
lockdep enabled in the kernel config. Maybe this lockup is triggered by
lock inversion.
