           Summary: Black screen when the i915 kernel module is loaded.
                    Graphics card IDs 8086:27ae.
           Product: Drivers
           Version: 2.5

Dmesg with drm.debug=0xe parameter.

Compiled vanilla 3.6.11 kernel loaded on a Terra all in one device.  

When KMS i915 kernel module is loaded, all I get is a black screen.  The device
does not freeze and continues to boot.  This device was working with vanilla
2.6.34 kernel.

The device's motherboard is an MSI-7437 base board with an American Megatrends
Inc. BIOS, version 080015.  The graphics card is an Intel Corporation Mobile
945GSE Express Integrated Graphics Controller with PCI IDs 8086:27ae.

I will attach a dmesg with the drm.debug=0xe boot parameter as well as lspci
and other device information files.

Since I am one of the maintainers of 2XOS and can build kernels on the fly I
would be able to test any patches/suggestions that may arise.
