You are reading too many brochures. florin at bear:~$ cat /proc/interrupts CPU0 0: 127159010 XT-PIC timer 1: 33357 XT-PIC i8042 2: 0 XT-PIC cascade 5: 428317 XT-PIC ohci-hcd 8: 1 XT-PIC rtc 9: 0 XT-PIC acpi 10: 15679 XT-PIC advansys, ohci-hcd, CS46XX, radeon at PCI:1:0:0 11: 9387 XT-PIC ide2 12: 183902 XT-PIC eth0 14: 177460 XT-PIC ide0 15: 0 XT-PIC ide1 NMI: 0 LOC: 127159720 ERR: 125402 MIS: 0 The ohci-hcd thingie on IRQ5 is my USB mouse! It is (after the timer of course) the biggest source of interrupts in my system. If the system is loaded: playing music you get over nfs from a server and burning a cd and browsing (moving the mouse a lot), you might get lost interrupts. It just depends on how well the drivers share the irq line. A couple of years ago I was getting noise from the sound card every time a packet went through my ethernet card. And I couldn't do anything about it since it was a laptop, with all the interrupts wired to 11. The kernel and drivers imporoved a lot since then. There were also some problems back when X would grab the PCI bus and hold it too long, causing the dropped ethernet packets and noise over the music.
