does this error appear on older kernels?

Can you get a dmesg booted with "nouveau.debug=debug"?

thanks

dmesg with nouveau.debug=debug

Here is the debug log. By the way, this is exactly the same report as was
posted on the nouveau list "Kernel panic on nouveau during boot on NVIDIA
NV118
(GM108)" - I just duplicated it here after no response on the list (plus I
think here is the more appropriate place?)

Thanks for your help so far!

And yes this problem has been reproduced on v4.8, v4.11, v4.12-rc3. We don't
know of any working kernels.

--- Comment #4 from Karol Herbst <karolherbst at gmail.com> ---
can you also upload your vbios.rom file located in
/sys/kernel/debug/dri/0/vbios.rom ? And if you are up for it, install envytools
and do nvapeek 101000 as root? Second is optional, but may help us even more.

vbios.rom is empty. We will try to get envytools running now.

The nvapeek 101000 output is "PCI init failure".

test disabling pci link config twiddling

Can you give this patch a try?  It looks like things are working normally up
until we try to fiddle with the PCIE link configuration, and I'd like to
rule
this in/out as a culprit.

Sorry for the slow response.
We tested the patch against 4.13.rc5 and the issue is still there.

I don't suppose you'd be able to grab a mmiotrace[1] of the proprietary
driver
for me?  One of Nouveau might be useful also.

Sent partial dump from nvidia proprietary driver to mmio.dumps address:


I loaded the module and then started an empty X session.
Unfortunately with tracing enabled, this results in an instant hard hang
upon starting X, before it has rendered the black screen.

However I managed to capture these messages over the network up until
the point of hang.

Captured on Linux 4.13. No external displays connected. The all-in-one PC
has one internal LCD display.

This patch should (hopefully) help with the issues faced while tracing the
binary driver, it will apply to their kernel shim layer sourcecode that can be
found if you extract the installer package with --extract-only (and run
./nvidia-installer inside the extracted directory to build the patched kernel
module).
