i915 drm/kms crash

[Sven Geggus]

Hello,

I get the following crash on a Fujitu/Siemens ST6012 Tablet PC (kms enabled):

This is a vanilla Kernel (2.6.32.7)/ Debian testing system.

Linux (without framebuffer) and X.org used to work fine on Debian stable,
but I needed to upgrade for a newer Version of Mesa.

Regards

Sven

get a Windows operating system.
