Hi Michal
can you please try the bellow change[1]?
In addition, the bug/trace is in mlx5_ib driver code, so I CC rdma ML
(linux-rdma@vger.kernel.org).
thanks

Hi Shay,
I am afraid that the suggested change didn't help (I applied both patches now on top of 6.8.9), kernel still crashes with very similar (if not the same) traces, please see attached.

Michal
