[coreboot] S3 fails to suspend after wake up from USB keyboard

[WANG Siyuan]

Hi,
I am trying to debug an issue on Parmer.
1) use "pm-suspend" to suspend.
2) use USB keyboard to wake up.
3) use "pm-suspend" to suspend. FAIL To SUSPEND.

After wake up by USB keyboard, I got some errors in dmesg:
[   55.585935] Disabling IRQ #9

I don't know why this is happened. It seems that ACPI method (_PTS,
_WAK) have nothing to do with suspend and wake up.

Does anybody can help me?
1) What is the workflow of USB keyboard wake up from S3?
2) What are differences between power button wake up and USB keyboard wake up?

dmesg:
