SYMPTOMS

Consider the following scenario:

You run a Windows Embedded CE 6.0 R3-based image that contains the Storage Manager components on a target device.
A thread calls the MountPartition function. For example, this happens when you mount an external storage device manually to the Windows Embedded CE 6.0 R3-based device and an application calls the function to mount the storage device.
Another thread calls the CeResyncFilesys function. For example, this happens when you repeatedly attach and detach the external storage device to the Windows Embedded CE 6.0 R3-based device.

In this scenario, a deadlock may occur between the two threads. Additionally, the applications that produce these threads may stop responding.
