FIX: A Stop error or a crash occurs on the operating system when you profile an application by using Visual Studio 2008 Service Pack 1
You may experience a Stop error, or the operating system may crash when you create a profile of an application by using Microsoft Visual Studio 2008 Service Pack 1 (SP1). The problem occurs when the following conditions are true:
- You use the sampling profiling method.
- The computer is running on the Intel Nehalem processor.
This problem occurs because the sampling profiler uses a driver in the operating system. However, the Intel Nehalem processor was created after the release of the 2008 version of the profiler. Because the sampling feature of the profiler is specific to the driver per processor, it was not possible to be completely compatible with the Nehalem processor before the release.
