I currently run a MythTV box based on an Athlon XP 1600+ / MSI K7T266. I know this is an under-powered system by recent standards, but it does SD very well.
For the entire time I have had this setup running Myth I have problems with spurious IRQ interrupts. Under linux I have to boot with the "irqpoll" kernel option to get it to work without errors.
Should the PCI bus be able to handle this load (3 tuners / pcmcia NIC / AGP) without having to poll the interrupts? Or is this buggy hardware / BIOS? Or is it a PCI bus limit?
If it is buggy hardware I would be looking to upgrade to something like a sempron 3100+ / DFI LANPARTY UT nF3 250Gb (undervoltable/ passive cooling). I am open to other suggestions for motherboards.
However, If I am starting to approach the practical bandwidth limit of the PCI bus, am I going to end up with a similar problem no matter which motherboard I choose.
