Hi,
whenever I try to test a reliable connection using "ibv_rc_pingpong -d
mlx5_0" to start the server side the test immediately stops with
"Couldn't create CQ". Since I couldn't find a solution for this problem
in one week I would like to ask if someone has encountered this error
before or knows a way of troubleshooting it. Just to be sure I updated
the controller to its latest firmware (16.29.2002) today, but the error
remained the same.
