Within a Thread in IRQL 0 the completion routine, triggered from an IRP, for a WskSendTo call is sometimes in IRQL 2 and sometimes in IRQL 0. This seems mighty strange to me. Does anyone know if this is normal behaviour?

This is normal behavior.
Completion Routines may be called directly in the call to the routine or from any other context.
See the MSDN for a description of IoCompletion routines.
