Nvidia Nouveau driver: GPU0 lockup

I have a problem with my installation or GPU.
During shutdown I see the message GPU0 lockup ....

Is this a problem with the noveau driver or the graphics card ?

See NVIDIA Optimus - ArchWiki.

Symptoms: lspci hangs, system suspend fails, shutdown hangs, optirun hangs.
Applies to: newer laptops with GTX 965M or alike when bbswitch (e.g. via Bumblebee) or nouveau is in use.

Wiki suggests to add nouveau.runpm=0 to the kernel parameters. Edit /etc/default/grub as root and that parameter to GRUB_CMDLINE_LINUX_DEFAULT=. Update grub with sudo update-grub.

Actually, I am testing now.

Sometimes the error on reboot or shutdown does occur - even with nouveau.runpm=0.

Is the graphics card defective ?

How can I test, if the graphics card works correctly ?

The error: GPU0 lockup ... switching to fbcon only occurs on shutdown, not reboot.

I have done the GPU test under Windows 10: dxdiag and Furmark.
No problems found.

Can you try using proprietary drivers instead. Also see some search results about the error.
