But in that case the saa7134 will capture frames again once the signal is better instead of refusing to do anything until power-cycled. I've seen several reports on this already, but it didn't happen so far happens on any of my my systems, I have no idea what this might be ... Any error messages in the syslog? Does the card still produce any IRQs when locked (check /proc/interrupts)? Gerd -- Michael Moore for president!
