I'm having what I think is a PCI bus problem.
I have a ASUS P5B Intel 965 motherboard and a DVICO Fusion HDTV5 RT
adapter on the PCI bus. When this adapter is recording (anything) I see
pci_abort messages repeating in the /var/log/messages file. As a result
I see some minor video corruption during playback. I've installed the
adapter into a PCI slot that shares an IRQ with the onboard USB.
However, I've also disabled all USB support in BIOS, so the adapter is
the only thing on the IRQ, and still see the same errors.
Any suggestions for further troubleshooting? Is this a PCI bus quirk on
this motherboard? A copy of my .config is at
