This sounds almost exactly like the reboot issue I've been having. I'm using a AMD processor, but the motherboard is VIA chipsets. I am running CentOS. The kernel reports itself as 2.6.18, but there a lot of backporting in it.
I am going to start compiling vanilla kernels and see if I can find one where the PVR-500 is stable. I'm starting with 2.6.25 and working backwards. I am not willing to bet on my success. My issue could easily be a hardware problem. My gut says it's not, though. Jeroen Roos wrote: > Hello all, > > I have a PVR-500 card on a Via Epia EN15000 board.
