Hi,
I am writing a driver that needs to interact with the ACPI (ASL) code
(Operating System: Windows XP Professional - SP2).
ASL code is embedded in to the system BIOS and my driver registers a
call back by doing the following:
ntStatus =
devExtension->ACPIInterfaces.RegisterForDeviceNotifications(pAcpiPDo ,
(PDEVICE_NOTIFY_CALLBACK)ACPICallback,
(PDEVICE_EXTENSION)pDevExt );
The driver runs normally without any problem if Driver verifier is
disabled. But if I enable Driver Verifier for my driver, I get a blue
screen with 0x000000A3 stop code.
ACPI_DRIVER_INTERNAL
0x000000a3 (0x00000002,0x00090147,0x82015CE0,0x82015D98)
I couldn't get much info from the DDK help except that the BIOS could be
source of the problem. But I highly doubt this could be the issue since
my driver runs normally without Driver Verifier.
Any experience / pointers on how to debug this bug check?
Appreciate your help & time.
Thanks,
Vijay

ACPI_DRIVER_INTERNAL (a3)
The ACPI Driver detected an internal inconsistency. The inconsistency is
so severe that continuing to run would cause serious problems.
The ACPI driver calls this when the state is so inconsistent that
proceeding
would actually be dangerous. The problem may or may not be a BIOS issue,
but
there is no way to tell.
