Re: BSOD_PAGE_FAULT_IN_NON_PAGED_AREA

alexander is correct, you cannot reassign this value. this field is owned by the io manager. since the io manager owns it, it thinks it can free it, which it does on unload. since the buffer points to a constant in your driver's image and not from pool, it blows up.

You CAN'T do that... Why do you think you can?

Hi there people,

I have problem running the following driver code. It worked for sometime
but without no obvious reason whenever I try to stop the driver service
a BSOD appears with the PAGE_FAULT_IN_NON_PAGED_AREA error.
I found out that when I remove the set DriverName code the problem disappears
but the question is why.

I'm desperate I cant find a way to fix this thing. I load the driver
with the instdrv.In the Debug Viewer only the HI message apperars Any ideas?

Here is the code

VOID UnLoadMe(IN PDRIVER_OBJECT obj);
UNICODE_STRING us;

NTSTATUS DriverEntry ( IN PDRIVER_OBJECT theDriverObject, IN PUNICODE_STRING
theRegistryPath )
{

DbgPrint("HELLO");
RtlInitUnicodeString( &us, L"TEST\0" );
theDriverObject->DriverName=us;
theDriverObject->DriverUnload=UnLoadMe;
return STATUS_SUCCESS;
}


VOID UnLoadMe(IN PDRIVER_OBJECT obj)
{
DbgPrint("BYE");
}
