I seem to have the IOAPIC interrupt controller on my x86_64 system. When I 'cat /proc/interrupts' is says IO-APIC for all devices. Also, vector 2 (cascade) is no longer listed. My Digium devices are on vectors 17 and 19, with eth0 on 18, libata on 20, and ehci_hcd on 21. It seems every device has its own interrupt vector (irq?). Should I be concerned about this? Will I be having interrupt conflicts with this setup? Thanks, -- Michael Welter Introspect Telephony Corp. Denver, Colorado US +1.303.674.2575 mike@introspect.com www.introspect.com
