Hi UD, have tried but still no resolving yet.

I've even tried to install fresh reload the OS as well.

Thank you!

The server is DELL PowerEdge R610.

Hi UD, very happy to share with you that the issue is fixed once I upgraded the kernel to 4.8.0.53-generic from 4.8.0.52-generic.

Thank you very much to you and your team!
