Re: UEFI Payload Issue

Ma, Maurice <>

UEFI Payload from EDK2 2017 seems to be pretty old.

Below are some of my recommendations:
- Enable serial debug console in UEFI payload so that you don't depend on USB KB for input. Once you booted to Shell using serial console, further info can be collected to root cause USB issue.
- If you saw the hang at "[Bds]BdsWait(3)..Zzzz...", it could be timer related issue. I saw some instances where the ACPI timer base was reported incorrectly to UEFI payload and ACPI timer base was wrong. That would cause the dead loop in delay function.
- Try out the latest UefiPayload in EDK2 to see if it works for you.
