On WHL after booting to Windows, SCI interrupt storm was seen due to GPE event 111 (2-tier GPE event). This event needs to be handled when RTD3 table is implemented. However, current code has _L6F ASL code without RTD3 table. This causes the SCI event to be enabled in Windows. Since there is no real handler to clear the SCI event, SCI interrupt storm will occur. This patch commented out the _L6F ASL method. Tested this on WHL. The CPU utilization drop down from original 10% to close to 0% for system interrupts.

Slim Bootloader
Welcome to the Slim Bootloader project!
Slim Bootloader is an open-source boot firmware solution, built from the ground up to be secure, lightweight, and highly optimized while leveraging robust tools and libraries from the EDK II framework.
What is a Bootloader?
Just like a typical BIOS, Slim Bootloader is the piece of software responsible for initializing the core hardware components of the system when it is powered on, followed by the loading and launching of the desired operating system.
Slim Bootloader offers the flexibility for OEMs, device manufacturers, and hobbyists to isolate, configure, and optimize for the the specific requirements of the system thereby achieving unparalleled boot performance and minimizing firmware footprint.
