Quick summary is that I have a GeForce8400 installed in a Thinkcenter with on-board i915 graphics. 2.6.38 fails to boot, 2.6.37rcX is OK. There appears to be some interaction between the nouveau and i915 drivers, disabling the i915 enables system to boot. I am unable to disable on board graphics in the BIOS (IBM special).
