linux 3.4 + nouveau + X11 = fallback to vesa

Hi there! I'm getting an issue with my NVIDIA GeForce 8400M GT card, running the latest kernel and nouveau driver.

Linux rx 3.4.3-1-ARCH #1 SMP PREEMPT Mon Jun 18 08:07:54 UTC 2012 i686 GNU/Linux

dmesg shows me the following:

[    1.774518] nouveau 0000:01:00.0: enabling device (0000 -> 0003)
[    1.774981] [drm] nouveau 0000:01:00.0: unsupported chipset 0xffffffff
[    1.775266] nouveau: probe of 0000:01:00.0 failed with error -22

And it seems like I have corrupted configuration space saved by the kernel before suspend (https://github.com/Bumblebee-Project/Bu … Developers), but it's something different - reboot does not help.

The driver is loaded and listed by lsmod:

nouveau               715415  0 
button                  3614  1 nouveau
video                   9883  1 nouveau
mxm_wmi                 1101  1 nouveau
wmi                     7259  2 mxm_wmi,nouveau
i2c_algo_bit            4615  1 nouveau
drm_kms_helper         29203  1 nouveau
ttm                    46507  1 nouveau
drm                   170915  3 ttm,drm_kms_helper,nouveau
i2c_core               16653  6 drm,i2c_i801,drm_kms_helper,i2c_algo_bit,nouveau,videodev

But X11 is always starting with the vesa driver, although /var/log/Xorg.0.log contains no errors on this subject.

[   345.156] (II) LoadModule: "nouveau"
[   345.156] (II) Loading /usr/lib/xorg/modules/drivers/nouveau_drv.so
[   345.156] (II) Module nouveau: vendor="X.Org Foundation"
[   345.156]    compiled for 1.12.2, module version = 1.0.1
[   345.156]    Module class: X.Org Video Driver
[   345.156]    ABI class: X.Org Video Driver, version 12.0

Please help to get those things working again.

Give what you have. To someone, it may be better than you dare to think.

rx: Please try that with X shutdown and from a tty.

rmmod nouveau
modprobe nouveau force_post=1

Same thing as at the boot time:

[drm] nouveau 0000:01:00.0: unsupported chipset 0xffffffff
nouveau: probe of 0000:01:00.0 failed with error -22

Re: linux 3.4 + nouveau + X11 = fallback to vesa

So, comparing dmesg's of 3.3.8 and 3.4.3 shows the following: http://pastebin.com/eHZMBNXP

Where we have:

+ACPI: EC: GPE storm detected, transactions will use polling mode

, a lot of pci devices with missdetected BAR [mem] and finally:

-pci 0000:01:00.0: Boot video device

It seems to be an ACPI/PCI issue.
