ACPI Errors

I'm getting these error messages on the startup screen. This started right after I upgraded my kernel to 4.9.

[    0.524702] PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug
[    0.524770] platform wdat_wdt: failed to claim resource 4
[    0.524776] ACPI: watchdog: Device creation failed: -16

[    9.779912]ACPI Error: [\_SB_.PCI0.GFX0.DD02._BCL] Namespace lookup failure, AE_NOT_FOUND (20160930/psargs-359)
[    9.779924] ACPI Error: Method parse/execution failed [\_SB.PCI0.RP05.PEGP.DD02._BCL] (Node ffff88014a8f8d70), AE_NOT_FOUND (20160930/psparse-543)

What do these messages mean?
How to correct these?
