I currently cannot boot Linux (Fedora 31) using either TianoCore payload on a skylake laptop. I've received the error message "NMI watchdog: watchdog detected hard lockup on CPU #" once, but it's otherwise just been boot-looping.

I've tried enabling the legacy 8254 timer, but I don't think it helped. This is for a port in progress that did previously boot properly.

Does anyone have an idea what might be wrong with it?

Thanks.
