PEX_WAKE_N signal can't wake up system

Hi NV

I tried wake-on-lan for our PCIE ethernet module (intel I210) on AGX-Xavier with Jetpack 5.0.2.
Found that the PEX_WAKE_N signal can’t wake-up the system.
But the same method and procedure worked fine on AGX-Xavier with Jetpack 4.6.1.

Before the test, I have checked the wake-up source for the PCIE interface existed.
And the system could read PEX_WAKE_N input signal by GPIO successfully.
Here is my test step:
(1). Put system to sleep by command “echo mem > /sys/power/state”
(2). Pull the PEX_WAKE_N from high level to low level (ground).

Is there any suggestion or idea from NV about this issue?

I checked Jetpack 5.0.2’s release note.
Seems there is an issue 3447132 "Wake-on-Lan is not supported in release 35.1 in the “fixed issue list”.
Is it the related issue?
