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);
}
