System hang when login ubuntu desktop with NVMe SSD plugged
I have the same issue.
I am running:

Linux version 4.4.132-1077-rockchip-ayufan-gbaf35a9343cb ([email protected]) (gcc version 7.3.0 (Ubuntu/Linaro 7.3.0-16ubuntu3) ) #1 SMP Mon Jul 30 14:06:57 UTC 2018

Ubuntu 18.04.2 LTS \n \l

if I don't login to the xfce4 desktop then it runs just fine.

I found if I unplug the PCIe card, I can login to xfce4 desktop and everything works fine ( but no M.2 drive available - obviously ).
If I plug in the PCIe card but don't log in to the GUI Desktop, I can boot the rockpro64 and can ssh to it from my laptop.

It doesn't matter if the drive is mounted or not.   

This only happens when the PCIe card is plugged in and I login to the GUI Desktop.   If I don't login to the GUI Desktop,  the machine continues to run, no hang.

I've looked through syslog but can't find any reason for this.
