Crash Windows 8 switchable graphic (Intel + 7670M)

I've just set up a new laptop (Samsung NP350 with a Sandy bridge CPU + Radeon 7670M) with VS2012 using Windows 8.

(just to be able to test the Binding of a subrange of a CB feature, the code is DX10.1 compliant)

Running my test code gives a crash, either in x86 and x64 targets.

The same code runs fine on a least 20 different computers (with ATI 4550, 5850, 5870, 6320M, 7870, NVidia (various models), Sandy bridge IGP) either in x86 and x64 using Windows 7 (VS2010)

On windows 8, it crashes always at the same point, after running about 20 seconds without any input (each frame executes the SAME code, with the SAME data)

on the x86 target, it crashes while calling DeviceContext->ClearState()

the callstack for the x64 target is less explicit, but seems to be related.

I don't know if it's related to the ATI driver but it may be ...

(I can send you the necessary files if you want to reproduce it)(

Thanks in advance if you can help me
