Subject: [Bug 196189] New: [BISECTED][REGRESSION] Nouveau on NVA8 renders the system unusable
Date: Sun, 25 Jun 2017 12:03:13 +0000	[thread overview]
Message-ID: <bug-196189-2300@https.bugzilla.kernel.org/> (raw)

https://bugzilla.kernel.org/show_bug.cgi?id=196189

            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.
