I've got two on their way (and one in production on a machine running a vanilla 2.4.20+kraxel patches+LML's patched bttv) that I can test with, but I was just curious. Along those lines, has anyone else here experimented with this card? My problem is that there is something of a memory leak in the driver somewhere; the machine will run stable snapping a frame every 2 seconds (rotating amongst the 8 ports) for about 36 hours; after that time the snap times become longer, the load average goes up without any commensurate increase in any other top-monitored parameter, and the machine eventually thrashes itself to death, with captures taking 15-20 minutes each to complete. I have worked around this by cronning a reboot every day, but that is a serious kludge. I'm using the webcam distributed with the xawtv that came stock with RH 8.0, setting it to capture and upload a single frame, and cycling the inputs with a shell script that calls webcam with the appropriate .webcamrc for the input desired. Full motion video crashed the kernel with a panic the first time I tried it (using the patched motion distrubtion provided by LML). Machine is an Intel 440FX Pentium Pro 200 with 64MB RAM running Red Hat 8.0 (minus redhat's kernel). I intend to upgrade the RAM, but I'm not sure it's a RAM problem. The machine for the second LMLBT44 is a Dual Pentium II 300 on a 440BX chipset, so it might act differently. I have a dual PII 266 on a 440FX I can test with, though. For those who may not know, the LMLBT44 is a four-way BT878-based card with a PCI bridge integrated onto the card. It has eight video inputs on BNC's, along with some digital inputs and outputs for switching, etc. -- Lamar Owen Pisgah Astronomical Research Institute
