Robert, This is likely a problem with the BIOS' or linux kernel configuration of the PCI bridge chip or interrupt controller in your system. If you can test the mobo with a Window install to eliminate bad mobo hardware, you should. You can also muck with BIOS PCI settings and hope to get lucky. At that point you should probably post your problem to the linux kernel mailing list (or some other linux PCI mailing list), with a subject of "Legacy PCI interrupts not working on Intel DH77KC mobo". Explain that you have two different tuner cards, supported by two different drivers and the kernel is not receiving interrupts for either of them. Provide your kernel version and the output lspci -nnnvvv as root and provide a link to this thread. List members may request the complete output of dmesg or /var/log/messages Regards, Andy _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
