	I tried to run some Link DMA transfers in low priority while servicing
Eventreq interrupt in high priority. However, as soon as I service the interrupt, all DMA transfers stop until I finish and deschedule the interrupt routine.
I thought once the DMA is set, the link engines will take care of the link
transfer with no processor intervention, no matter whether you are in high or
low priority. Is this the way that transputer supposed to response or am I
missing something ?
