When we contacted Hauppauge regarding the stability issue, they
recommended upgrading to the latest firmware dated Mar 26 2012.
We *think* this has improved stability, but it certainly hasn't
fixed it completely.

Upgrading the firmware requires a Windows PC -- see

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.
