Nouveau - Jan 2017 - Erros and warning using kernel 4.10-rc2

Hi guys,

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

[marcos at 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:

Please, let me know if this information is useful and/or you need more tests or
different config to solve these ones.

Thanks!

could you grab the vbios from /sys/kernel/debug/dri/1/vbios.rom and
maybe also do a mmiotrace with the nvidia driver (using bumblebee or
second X server by hand or so)?

thanks

Hi Karol,

sorry for the delay.

here is my vbios file:
https://drive.google.com/open?id=0B_-jCMJSxUqBMXZobldiY2xIV00

about the later, I need to check how to do it, since I don't have any
experience using bumblebee and/or different X configs..

But I can check how to do it in the next few days. Hope this can help to solve
these issues!

Thanks,
