Hi guys,

I don't know if it is useful to just post some random kernel warnings/errors, but here they are:

[marcos@xfiles ~]$ journalctl -b -p 3 | grep nouveau
Jan 08 15:37:05 xfiles kernel: nouveau 0000:04:00.0: volt: couldn't find speedo value, volting not possible
Jan 08 15:37:05 xfiles kernel: nouveau 0000:04:00.0: bus: MMIO write of ffff981f FAULT at 6013d4 [ IBUS ]
Jan 08 15:37:05 xfiles kernel: nouveau 0000:04:00.0: DRM: Pointer to TMDS table invalid
Jan 08 15:37:05 xfiles kernel: nouveau 0000:04:00.0: DRM: Pointer to flat panel table invalid

In this first case, this message comes from nvkm/subdev/volt/gf100.c, and I haven't seen this message in 4.8 for example (using fedora 25 kernel at least)

The second one already appears on 4.8 as well, and I think it appears in function gf100_bus_intr of nvkm/subdev/bus/gf100.c

And other two ones are already appearing in in my laptop for quite some time also, and they came from nouveau_bios.c.

This is my nvidia board:
