kernel report error on nouveau driver for Acer Aspiere A715-71G-54LH, causing hanged machine when shutdown

[Christian Salazar]

Hello everybody. this is the first time i report a issue here. Sorry my broken english :)

Recently i bought a a Acer Aspire A715-71G-54LH with NVIDIA graphic card, by default after installation it runs nouveau driver. The graphics looks fine but suddently strange things start happeing:

+ computer hanged at startup (some times, sometimes not)
+ shutdown hanged after clicking the "logout" button (all the times)
+ shutdown hanged after calling "shutdown -h now" command (all the times)

All this issues happened when nouveau driver was active, after changing to a nvidia propietary driver then it starts working fine again with no issues at all.

Resume:

+ (NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev a1))
+ Linux version 4.15.0-23-generic (buildd@lgw01-amd64-055)
+ Ubuntu 4.15.0-23.25-generic 4.15.18

By running "journalctl -b -1" it shows the error (please see attachments), this log happened when nouveau was active.

The nvidia-driver produces no error at all)

Thnku very much.
