FIX: A deadlock may occur when two file system drivers are loaded after each other in Windows CE .NET 4.2 (867775)


The information in this article applies to:

  • Microsoft Windows CE .NET 4.2

SYMPTOMS

A configuration with a file system driver (FSD) is loaded and active in Microsoft Windows CE .NET 4.2. When a second FSD is loaded, a deadlock may occur.

For example, a platform with the binary ROM image file system (BinFS) may experience a deadlock when a storage device that uses the FAT file system (FATFS) is mounted or is unmounted.

CAUSE

This problem occurs when two threads that are in the file system module try to take a critical section at the same time.
