Q237699: Error Message: Stop 0x0000000A in ScsiPort.sys on SMP Systems

Article: Q237699
Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): kbWinNT400PreSP7Fix

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you run a program that makes a ScsiBusScan() call (for example, Disk
Administrator), the following error message may be displayed on a blue screen:

  STOP 0x0000000A (0x0000000C, 0x0000000A, 0x00000001, 0x801de690)
  IRQL_NOT_LESS_OR_EQUAL
  Address 801de690 has base at 801de000 - scsiport.sys

NOTE: The fourth parameter may vary from system to system, but is always based in
Scsiport.sys.

CAUSE
=====

The problem may occur if there are multiple programs issuing the
IOCTL_SCSI_RESCAN_BUS I/O control at the same time. There is a race condition
that can cause the same request to get issued twice.

==========
