DeadLock in filter device.

hello ,everyone!
I built a filter driver like filemon on a ntfs system.
And make a new IRP_MJ_QUERYINFOMATION irp when filter device received a
IRP_MJ_WRITE IRP.When I sent IRP_MJ_QUERYINFOMATION before passthru
IRP_MJ_WRITE IRP ,enter a deadlock in IoCallDriver.
why?

Do you send the IRP to the lower driver only or
to the top of the stack ?
