Now, this is one we have an issue with: it's got a bttv card, and motion running on it. It's a Dell PE R720. For some reason, it has never liked the card: 20 min after reboot, it says fatal bus error... but nothing's wrong, and it runs just fine. Well, expect that we need to keep it on the 2.6.32-431.20.3 kernel, because *everything* later, it randomly starts rebooting, several times a day. But we've never had anything like this, and I've never seen anything like this: the bttv module was throwing a ton of IRQ lockup errors. Restarting motion didn't help. So I was wondering if the issue was with the bttv kernel module, so I rmmoded that, then modprobe bttv... and that was all she wrote. The system lost network connectivity. Ok, I go over to the rack, and plug in the monitor-on-a-stick, and that's where it got very strange, and I've never seen anything like this: I turn up the monitor... and see it announcing it had seen a new USB device (the keyboard)... and no login, it kept printing copying data [<percentage done>%] When it hit 100%, it rebooted. So - has anyone ever seen this behavior? Anyone have an idea what it was copying? mark

Currently, I have, in /etc/modprobe.d/bttv: options i2c-algo-bit bit_test=1 options bttv gbuffers=16 card=98,98,98,98,98,98,98,98 radio=0,0,0,0,0,0,0,0 tuner=4,4,4,4,4,4,4,4 chroma_agc=1 combfilter=2 full_luma_range=1 coring=1 which is something I got from googling as to how to get it working. Think there's something in that - the first line? that is not a good thing? mark mark
