STOP 0XA Caused by Race Condition in VDM and Process Delete

 Last reviewed: December 23, 1997
Article ID: Q178471
The information in this article applies to:
  • Microsoft Windows NT Workstation version 4.0
  • Microsoft Windows NT Server version 4.0

SYMPTOMS

When running 16-bit programs that require the Virtual DOS Machine (VDM). the following STOP error may occur: 

   Stop 0x0000000A (0x00000084, 0x00000002, 0x00000001, 0x80003D4A)
   Hal.dll.
This problem is most likely to occur on systems with more than one processor.

CAUSE

A race condition exists between process delete and delayed virtual interrupt processing. This causes a NULL parameter to be passed to the Hardware Abstraction Layer (HAL) acquire spin lock routine.

RESOLUTION

To resolve this problem, obtain the following fix or wait for the next Windows NT service pack.

This fix should have the following time stamp: 

      12/22/97  02:41                 938,880 Ntkrnlmp.exe (Intel)
      12/22/97  02:41                 918,912 Ntoskrnl.exe (Intel)

      12/22/97  02:38               1,399,744 Ntkrnlmp.exe (Alpha)
      12/22/97  02:38               1,372,352 Ntoskrnl.exe (Alpha)
Apply Ntoskrnl.exe if the target computer has only one processor.

Apply Ntoskrnlmp.exe if the target computer is a multiprocessor system.

NOTE: After copying Ntkrnlmp.exe to the target computer, rename it to Ntoskrnl.exe.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.
