Comme= nt # 38 on bug 10056= 7 from John Walicki 
The nouveau driver on my ThinkPad P50 (running RHEL 7.7 with a
5.2.11-1.el7.elrepo.x86_64 kernel) just hung up with this same error.

What is possibly interesting is that in /var/log/Xorg.0.log
there was a mouse event that matches exactly with the timing of the nouveau
errors.

[150270.473] (II) event8  - Logitech USB Receiver: SYN_DROPPED event - some
input events have been lost.

The [bracket] is a timestamp which indicates the time since the system last
booted, in seconds. So 150270 is 29 seconds after the 09:04:19 timestamped
line.=20
09:04:19 + 29 seconds is 09:04:48
The nouveau driver hung at that time (see /var/log/messages timestamp above)
Not certain if that was cause or effect of the video driver hang.

I was able to ssh into my system to reboot.
