Cause

This issue occurs when the virtual memory becomes fragmentized on a computer that is running an x86 version of Windows Vista or an x86 version of Windows Server 2008. When a user puts the computer into hibernation by using physical memory, a large, contiguous virtual address space is required. Because of virtual memory fragmentation, and also because of the 32-bit architectural limitation, the request for a large, contiguous virtual address space can fail. That failure causes Stop error 0xA0.
