Hi Yu :

I was not able to boot the BXT-P with the option "init=/bin/bash" because
simply the DUT does not boot, it always stop in initramfs prompt, on the other
hand i was able to boot with "nomodeset and text" options in the grub.
So once there i did one by one command and then i send the DUT to sleep (echo
mem > /sys/power/state), and after each command the DUT returns (please see
dmesg.log and test.log)

As well i have to comment that i've update the BIOS version and KSC of my BXT-P

Ifwi       : 119.10
Bxt SOC    : A0
KSC        : 1.06
GOP        : 10.0.1022
Board ID   : APL RVP 1A
