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

ID: Q237699

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.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT 4.0 service pack that contains this fix.
