Can you get a kernel log with "nouveau.debug=debug" set please?

Also worth trying with "nouveau.config=NvForcePost=1" to see if that works around the issue.

Hi Karol, Here's the kernel log with nouveau.debug=debug.

It looks similiar to this one: https://bugs.freedesktop.org/show_bug.cgi?id=101322

please provide a dmesg booted with "nouveau.debug=debug" as well

We are working with new desktop that have the NVIDIA NV118 chipset.

During boot, the display becomes unusable at the point where the nouveau driver loads. We have reproduced on 4.8, 4.11 and linux master (4.12-rc3).

Dmesg log is attached.

Is this a known issue? Anything we can do to help?

Thanks
