Chocolate Milk: Interrupt Draining (2020/04/17)

Get the code: https://github.com/gamozolabs/chocolate_milk In this stream we polished our soft reboot code. There was an issue where we would return back to the BIOS PXE code with interrupts pending. This caused the PXE code to get whacked with an unexpected interrupt. To drain these pending interrupts, we actually had to cause them to get accepted by the processor. Fun problem!
