I've heard that too, about the drivers. lspci -vv will give you a<br>little more detail about the devices. How many capture cards do you<br>have?<br><br>It looks like the interrupt from the capture card is shared with your

<br>anything in particular, but it was just a quick look. I did notice that<br>their is apparently downloadable firmware for the 3000.<br><br>Are you specifying any special boot parameters to the kernel like<br>noacpi?<br>
