Every time you post a backtrace it is different.. The only commonality
seems to be that the CQ completion core appears to be processing
garbage, accompanied by these sorts of sketch kernel messages from mlx5:

My other guess is a mlx5 issue where it is returning CQ wrids it
should not return?
Leon?
I don't see anything changing in this area in rdma.git for-rc, so I
can't give you a guess on a patch, sorry.
Do you think this test ever worked for you? You said bisect, so I
assume so?
Jason
