Still valid for CentOS-7.2.1511 using kernel 3.10.0-229.20.1.el7.x86_64
(3.10.0-327.10.1 has missing symbols for mlx5 driver so I can't test).

I forgot to mention that the link http://permalink.gmane.org/gmane.linux.drivers.rdma/20239 provides the patch that fixes the problem.

@olahaye74

The patch you quoted is in the current CentOS-7 kernel (3.10.0-327.x). Please update your kernel (3.10.0-229.x) to the latest. We cannot provide support for older versions.

Unfortunately, as mentioned 4 messages above: 3.10.0-327.10.1 has missing symbols for mlx5 driver so I can't test.

Where did you get that mlx5 driver from? The in-kernel driver, mlx5_core, does not work for your hardware? Can you ask the provider to update their version to include RHEL/CentOS 7.2?

As mentioned earlier, we cannot support older kernels. If you must stay with the -229 kernel, you may want to consider building a patched version yourself.

We are also noticing this with the newest kernel series (3.10.0-327.13.1) and a GPFS/Spectrum Scale filesystem served over IB.

How about the current kernel 3.10.0-327.36.3.el7? The 7.3 kernel (3.10.0-514.el7) will be released soon. Please report back if the issue persists with any of the newer kernels.

We are still getting this issue with kernel-3.10.0-514.2.2.el7.

pkenyon (reporter)

Still an issue with 3.10.0-514.10.2.el7.x86_64. In our case, this happens with mlx5_core from distribution.
