DXGI_ERROR_DRIVER_INTERNAL_ERROR on DrawInstanced() method at feature level 9_3

I've got following problem with DrawInstanced() call in my DirectX 11 code. When I call DrawInstanced() using feature level 10_0 or higher, everything works as expected, but when I switch to feature level 9_3, I get following error in debug output:

D3D11: Removing Device.
D3D11 WARNING: ID3D11Device::RemoveDevice: Device removal has been triggered for the following reason (DXGI_ERROR_DRIVER_INTERNAL_ERROR: There is strong evidence that the driver has performed an undefined operation; but it may be because the application performed an illegal or undefined operation to begin with.). [ EXECUTION WARNING #379: DEVICE_REMOVAL_PROCESS_POSSIBLY_AT_FAULT]

According to these msdn docs, Instancing should be supported on Directx 9_3 feature level. What is going on?

It turns out that while Instancing is supported on feature level 9_3, the only api that works is DrawIndexedInstanced as per msdn, so I had to adapt my code to work with indexed instancing.
