Thinkpad E14 : Cannot suspend/shutdown system

I have a thinkpad E14 on which suspend and reboot do not work. The system wakes up in 2-3 seconds when I suspend it and reboots whenever I try to shut it down.
I had posted about it earlier as well, but after arch and bios update it started working again. The older thread is here : https://bbs.archlinux.org/viewtopic.php?id=262860

After that, it was working for quite a time but then stopped working again. I suspected that an arch update might have caused it again so I tried rebooting with other linux distributions from a live usb stick, but still the problem persists.

 echo freeze > /sys/power/state

works,

 echo mem > /sys/power/state

does not.


System details :

Arch linux standalone installation

Kernels tried : linux, linux-lts, linux-zen

Other os tried : Kubuntu, Linux mint (from live usb)

Troubleshooting methods tried with main arch installation:

1. Disabling everything in

 /proc/acpi/wakeup 

2.

echo 0 > /sys/power/pm_async

3. Uninstalling tlp.

I have the dmesg and ftrace logs from the time it was working and also from when it stopped working, but I don't see any difference in the
dmesg logs and I do not know how what to do with the ftrace logs.  These logs were generated from suspendresume  tools described on
