Solution

The TSC_DEADLINE message is expected on the PXIe-8840 Quad-Core controller. It has no impact on the operation of the controller. Intel released a patch, but it is not included in the PXIe-8840 Quad-Core BIOS because it does not impact the controller's performance.

This TSC_DEADLINE message could be ignored, and the PXIe-8840 Quad-Core can be used as usual.

And this message can also appear when you use PXIe-8840 Dual-Core system. You can still ignore this.
