I was just about to ask a similar question... How do I have a better interrupt table (no or less shared intrerupts) with ACPI? My system (just rebooted) says: $ cat /proc/interrupts CPU0 0: 1434691 IO-APIC-edge timer 1: 5158 IO-APIC-edge i8042 8: 2 IO-APIC-edge rtc 9: 0 IO-APIC-level acpi 14: 8097 IO-APIC-edge ide0 15: 959 IO-APIC-edge ide1 19: 105118 IO-APIC-level nvidia 20: 17455 IO-APIC-level ehci_hcd, eth0, NVidia nForce2 21: 0 IO-APIC-level ohci_hcd 22: 16156 IO-APIC-level ohci_hcd NMI: 0 LOC: 1434624 ERR: 0 MIS: 0 The "problem" here might be IRQ 20 when I am using my scanner@4800dpi (USB2.0, Epson GT-X700) writing the output via NFS (through eth0). Will test the numbers some other time.
