Nouveau - Sep 2018 - System hang on Alienware 13 with NVIDIA GP106M

I do not know how to debug this situation. Nothing appears in 
/var/log/messages. I miss the serial port:-(

I executed a journalctl -r, and saw an error:
kernel: nouveau 00001:01:00.0; Refused to change power state, currently 
in D3

The last message before reboot was:
kernel: watchdog: Bug: soft lockup - CPU#0 stuck for 22s! [ntpd:3265]

I have a pair of these Alienware 13 laptops, and would be willing to 
lend you one for evaluation if that is appropriate.

Please get back and we can discuss details.

Alienware 17 r5 also with same graphics (GP106M and Intel 3e9b) does 
boot from same disk. I look in hwinfo --gfxcard and it says both the 
Intel (on i915) and the Nvidia (nouveau) are both present. What command 
tells me which driver is being used?

Thanks.
Don

We've seen a number of power management and secboot issues with the
Pascal-series mobile GPUs.
Without a command line it is hard to debug remotely, but see, as one
possible example: https://bugs.freedesktop.org/show_bug.cgi?id=100228

Can you try booting with a kernel command line that includes
"nouveau.runpm=0" as a debugging step.
