In my System it happens only with AMD64 port, before I was using x86 port and all work great, I have an EMT64 capable processor and runs debian great, all services work fine except xserver-xorg with driver i810, let me say that the error is just when unloading X, before that I can reach my desktop, use the Render, 3D accel, Composite Extension, Compiz etc but when Shuts down the Computer I get a Kernel Panic, I think to set the driver to VESA and work but haven´t DRI, 3D Accel, Composite etc.

My Hardware is:

- Celeron D 3.6 GHz EMT64
- ASRock 775i65G
- Intel® 865G Chipset
- Integrated Intel® Extreme Graphics 2 (intel 82865G Graphics)


The error screen message wite some like:
