humbleZheng, I just received an update on this matter.

While we are reviewing your case, we just wanted to confirm:

What is the procedure or process that you are doing or attempting to do that shows the error?

What is the hardware and software required to reproduce the issue?

Is the issue only visible on new drivers? 

When switching to an older driver is the problem the same? Please provide the specific version of the drivers that show the issue.

Please attach the SSU report so we can verify further details about the components in your platform, check all the options in the report including the one that says "3rd party software logs":
