We *think* this has improved stability, but it certainly hasn't fixed it completely. Upgrading the firmware requires a Windows PC -- see http://www.hauppauge.com/site/support/support_hdpvr.html On 13 Oct 2012, at 16:28, Jonathan wrote: > It may be a coincidence but I since I started using irqbalance ( > https://code.google.com/p/irqbalance/ ) my HD-PVR has been completely > stable. Before that I was experiencing daily lockups. Interesting. You definitely didn't upgrade the firmware around the same time? We think the stability is worse when the Linux PC is heavily loaded: We do real-time image processing on the video stream from the HD PVR, so the CPUs are maxed out, and we get frequent lock-ups. We also think the lock-ups are more frequent when we have several HD PVRs connected to the same PC, all running at the same time. I'll have to try this irqbalance. --Dave. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
