We developped a modulator card and device driver for linux. The card is a PCI card. When installed in an IBM E-server, dual processor xeon computer, the linux kernel does not receive any interupts. If I cat /proc/interrupts, the card is assigned interrupt 10 on the XT-PIC. The only other device assigned to the XT-PIC is cascade. When we check the card's intterupt line with an oscilloscope, we see that an interrupt is being generated. A temporary work around is to use the noapic flag with the kernel. I am wondering if there is a special call when requesting the interrupt that I can use to get the interrupt to go through the APIC so I don't need the noapic flag? -- Kendrick Hamilton E.I.T.
