Well, looking through the lessons of the past: http://www.google.com/search?q=ivtv+PVR-500+VIA+reboot http://www.gossamer-threads.com/lists/engine?list=ivtv&do=search_results&search_forum=forum_2&search_string=VIA+ivtv+reboot+PVR-500&search_type=AND you are not the first to have a problem with a VIA PCI chipset and the Hint Corp PCI bridge on the PVR-500. The reboot is caused by hardware interactions, causing the VIA PCI chipset to decide to reboot the system. Those detremental hardware interactions are set in motion by the ivtv driver, CX23416 firmware, and kernel software. What are the software actions causing the reboot? Who knows... Without detailed chipset data from VIA, details on the Hint Corp bridge on the PVR-500, and details on how your BIOS and the linux kernel are configuring those chipsets, troubleshooting the issue to the root cause through analysis and hypothesis testing has low probably of being successful in any reasonable timeframe. (The hours you may spend troubleshooting could cost more in labor, than buying two PVR-150's off of eBay.) Unfortunately this is a system level issue with many unknowns, little documentation available, and very few test points from which to gain insight. The reboot by hardware means no diagnostic information can be recorded to disk or a serial port when the problem happens. I can say that with the new kernel you are using, the implications of these messages looks worth investigating: IRQ 17/ivtv0: IRQF_DISABLED is not guaranteed on shared IRQs IRQ 18/ivtv1: IRQF_DISABLED is not guaranteed on shared IRQs Other than digging into that, you can try what others have tried in the past in the links above. (Forgive me, maybe I'm just in a pessimistic mood this morning.)
