Symptoms
Consider the following scenario:
-
You enable Driver Verifier on a computer that is running Windows Server 2008 R2 and that meets the following conditions:
-
The computer has four or more processor sockets. For example, the computer has four Westmere-EX processors.
-
The x2APIC mode is enabled in the BIOS.
-
-
You try to start the computer.
In this scenario, you receive the following Stop error code in the startup process if no debugger is attached to the computer:
STOP 0x0000005C ( parameter1 , parameter2 , parameter3 , parameter4 ) HAL_INITIALIZATION_FAILED
If you attach a debugger to the computer, an assertion failure occurs, and you receive the following error message instead:
A driver has enumerated two child PDO's that return identical Device Ids.
Cause
This issue occurs because the ACPI driver (Acpi.sys) incorrectly creates a duplicated physical device object (PDO) when some APIC IDs are larger than a value of 255.
