Symptoms

A computer that is running Windows Server 2008 may restart unexpectedly after you install Microsoft Multipath I/O (MPIO). Additionally, you may receive one of the following Stop error messages:
  • STOP: 0x000000D1 (parameter1, parameter2, parameter3, parameter4)
    The DRIVER_IRQL_NOT_LESS_OR_EQUAL
  • STOP: 0x00000050 (parameter1, parameter2, parameter3, parameter4)
    The PAGE_FAULT_IN_NONPAGED_AREA
Note
  • The four parameters that are in these error messages depend on the configuration of the computer.
  • Not all "0x000000D1" or "0x00000050" Stop error codes are caused by this problem.

Cause

This issue occurs because Microsoft Device Specific Module (Msdsm.sys) uses an incorrect variable to set the device information. This behavior causes the system to access an invalid memory address.
