为什么不能在onstartdevice()里面加断点?

驱动为pci卡,系统自动加载的.
驱动的其他函数加断点没问题,但一在onstartdevice()里面加断点,驱动运行到onstartdevice()
就会死机.如果不在onstartdevice()里面加断点的话程序正常运行. 能输出结果.

程序如下:
NTSTATUS CryptpciDevice::OnStartDevice(KIrp I)
{
ULONG r1;
t << \"ICE Entering CryptpciDevice::OnStartDevice\\n\";

NTSTATUS status = STATUS_SUCCESS;

I.Information() = 0;

// The default Pnp policy has already cleared the IRP with the lower device
// Initialize the physical device object.

// Get the list of raw resources from the IRP
PCM_RESOURCE_LIST pResListRaw = I.AllocatedResources();
// Get the list of translated resources from the IRP
PCM_RESOURCE_LIST pResListTranslated = I.TranslatedResources();

KPciConfiguration PciConfig(m_Lower.TopOfStack());
status = m_IoPortRange0.Initialize(
pResListTranslated,
pResListRaw,
PciConfig.BaseAddressIndexToOrdinal(0)
);
if (!NT_SUCCESS(status))
{
Invalidate();
return status;
}
    // The base class will handle completion

r1=m_IoPortRange0.ind(HDCR);
t << \"Suceess Read the register\" << \" HDCR =\" <<(ULONG) r1 << EOL ;
r1=m_IoPortRange0.ind(HSR);
    t << \"Suceess Read the register\" << \" HSR =\" <<(ULONG) r1 << EOL ;
r1=m_IoPortRange0.ind(DSPP);
t << \"Suceess Read the register\" << \" DSPP =\" <<(ULONG) r1 << EOL ;
return status;
}

这是为什么?
怎么解决?

不会吧，没有人回答？
