Nope no difference. I'd already tried this by stopping+starting dvbtraffic before I tuned... it doesn't help (I did try again tho adding the code to the driver to make sure). To recap: 1) start dvbtraffic -- IRQs are received from the saa7146. 2) tune and lock -- The IRQs suddenly halt for no reason. 3) restart dvbtraffic -- IRQs start again and everything works fine thereafter. And all only the very first time DMA is started on cold boot. _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
