SYMPTOMS

A crash occurs in the Ntfs.sys component on a computer that is running an IA-64-based version of Windows Server 2008 R2.

CAUSE

This issue occurs because a function in Ntfs.sys miscalculates the size of a flush request when a volume is mounted on the computer. When Ntfs.sys processes this flush request by using the incorrect size, invalid memory is accessed, and then the computer crashes.
