I've gotten my NI at-mio-16e2 working with the CVS version of the ni_atmio driver. I'm using kernel 2.4.25 with the rthal5 patch from rtai 3.0r3. I'm running aquistions at 500ksps on analog input ch0 only. My PII 400 will keep up just fine for a while and then after say 30 seconds of capture the card buffer will overflow. This in itself is probably a factor of my computer being to slow. However, after the buffer overflows the card becomes unusable. Any commands sent to the card terminate immediately. I can unconfigure the device with comedi_config but if I try to reconfigure it I get a kernel oops (killing interrupt handler). Is there any way that I can have an elegant buffer overflow? If I lose some data thats okay but I'd like to be able to continue to aquire samples. Perhaps something funny is happening on the interrupt after the buffer overflow? I don't mind debugging this myself but I don't really know where to start. Thanks for any help, David Carr
