Nouveau - Jun 2012 - [Bug 51157] New: GeForce GT 540M not working anymore

I suspect this is actually yet more fallout from a kernel 3.4 ACPI bug
actually... Nouveau in both logs has the same issues on your card, so it's
unlikely to be the cause of the behaviour change.

This is the kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=43168

Different symptoms, but both problems can probably stem from ACPI video support
not loading.

dmesg from kernel 3.4

I have a Sager NP5160 with Nvidia GeForce GT 540M Optimus card and running Arch
Linux.

Bumblebee was working fine with previous kernels, but it stopped working since
around kernel 3.1.  I tried solving this with the Bumblebee team at
https://github.com/Bumblebee-Project/Bumblebee/issues/156 but no luck.  I'm
thinking it may be something with the DRM module in the kernel.

Fortunately, it still works with the current LTS kernel in Arch (3.0.34) which
may help get some insight.  I'm attaching my dmesg from both the lts kernel
and
from the current kernel (3.4.2).  I'm also attaching my vbios.rom from
/sys/kernel/debug/dri/0/vbios.rom

Hi Diego

The errors in your logs could be related to the optimus solution on your laptop
- i.e. no displays physically connected to the nvidia card, thus causing Evo
issues. Have you tried booting in headless mode - "nouveau.modeset=2"
in your
kernel command line ?

Due to further changes in nouveau, we refuse to load due to -EBUSY (nouveau:
probe of 0000:01:00.0 failed with error -16)
Would you mind narrowing down the issue - which kernel introduced it, can you
bisect


Ben

In the latter kernel 3.4(3.3 is affected as well) we fail to load, leaving one
of the following to blame

---
    ret = nouveau_fence_init(dev);
    if (ret)
        goto out_pm;

    if (dev_priv->eng[NVOBJ_ENGINE_GR]) {
        ret = nouveau_card_channel_init(dev);
        if (ret)
            goto out_fence;
    }

    if (dev->mode_config.num_crtc) {
        ret = nouveau_display_init(dev);
        if (ret)
            goto out_chan;

        nouveau_fbcon_init(dev);
    }

Do problems persist with the latest kernels (e.g. 3.11-rc7 at the time of
writing)? If so, please attach a recent dmesg.

Thanks, it's working now with kernel 3.10.1.. I haven't tried with the
latest
but I will inform again if there's a regression.
