Problem:

Your changes to i915_stolen_to_physical() (commit: eaba1b8f3379b5d100bd146b9a41d28348bdfd09) expose the following problem

[ 2.272218] [drm:i915_stolen_to_physical] *ERROR* conflict detected with stolen region: [0x7f800000 - 0x80000000]

The fix, to reserve the stolen region in early x86 init, should be upstream already.

Atm it's stuck in drm-intel-fixes, but the pull request is already sent to Dave. So hopefully it'll land in upstream in a few days ... Poking Dave to speed stuff up ;-) -Daniel

Well, at least those two patches do fix the problem:

00100000-7f7effff : System RAM 00100000-005492f1 : Kernel code 005492f2-007d2fbf : Kernel data 0084e000-00dacfff : Kernel bss 7f7f0000-7f7f2fff : ACPI Non-volatile Storage 7f7f3000-7f7fffff : ACPI Tables 7f800000-7fffffff : reserved 7f800000-7fffffff : Graphics Stolen Memory
