            Bug ID: 196189
           Summary: [BISECTED][REGRESSION] Nouveau on NVA8 renders the
                    system unusable
           Product: Drivers
           Version: 2.5
    Kernel Version: > 4.11
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: daniel.otero@outlook.com
        Regression: No

Happens every single boot. The system becomes unresponsive seconds after boot
and the fan go to full speed until I force the system to shutdown.

Sometimes the screen stays completely black, other times it shows the console
login prompt (no X involved), but the system it's barely usable.

Bisected the offending commit, and resulted this one:

> commit 1e2115d8c0c0da62405400316f5499d909e479bc (refs/bisect/bad)
> Author: Alexandre Courbot <acourbot@nvidia.com>
> Date:   Tue Dec 13 17:11:20 2016 +0900
>  
>     drm/nouveau/pmu: instanciate the falcon in PMU device

No unusual kernel message until I enable "drm.debug=14" (find that out in
ArchLinux wiki, because I have no idea how to enable nouveau debug messages)
that this 4 error messages appear:

> nouveau 0000:01:00.0: bios: OOB 1 01452301 01452301
> nouveau 0000:01:00.0: bios: OOB 1 2223bb45 2223bb45
> nouveau 0000:01:00.0: bios: OOB 1 2223bb45 2223bb45
> nouveau 0000:01:00.0: bios: OOB 1 2223bb45 2223bb45

System details:
  > Arch Linux
  > CPU Intel Core i5 480M with Intel Integrated Graphics
  > GPU Nvidia GeForce 310M (with Optimus technology)

Thank you for your time.

--- Comment #1 from Ilia Mirkin (imirkin@alum.mit.edu) ---
The case of the OOB messages should already be fixed in mainline, and I suspect
they are unrelated to your issue. (I assume you see them on the commit prior to
the one you bisected to as well?)

To get more nouveau debugging messages, you can do nouveau.debug=debug or
nouveau.debug=trace.

Thank you for doing the bisect - that is very useful. Most graphics-related
bugs are actually not hosted on the kernel bugzilla. I wish there were some way
to indicate this. See

https://nouveau.freedesktop.org/wiki/Bugs/

for the proper procedure to file nouveau bugs (although I believe this holds
for all graphics drivers).

Sorry about that.

I already open a bug in the freedesktop bugzilla
(https://bugs.freedesktop.org/show_bug.cgi?id=101587) so I will close this one.

And, you're right, the OOB messages seems unrelated as it also appear in the
previous working commit.

Thanks!
