Intel Oxbow Hill reference board can be used for reproducing this issue. Steps for reproducing this issue.
1) Boot the Intel reference board with debug console connected to serial port.
2) LAN connection also need to be setup
3) login to Linux prompt
4) Note down the board IP address
5) Put in S3 state using the command, "echo "mem" > /sys/power/state"
6) Ping the board IP from the test PC.
The steps are from customer, I didn't reproduced this since I didn't find Intel Oxbow Hill reference board in VLM.
