For example: CPU0 0: 183247514 XT-PIC timer 0/47514 1: 67096 XT-PIC i8042 58/67096 2: 0 XT-PIC cascade 0/0 8: 82425669 XT-PIC rtc 0/25669 10: 163607273 XT-PIC uhci_hcd, EMU10K1 0/7273 11: 1912890 XT-PIC uhci_hcd, eth0 0/12890 12: 0 XT-PIC uhci_hcd 0/0 15: 244330 XT-PIC ide1 0/44329 The front panel USB port shares an interrupt with the sound card, the rear with eth0. Fome some of my testing it would be helpful if these just had numbers that I could mentally associate with a USB port. Right now I have to move the mouse and watch the interrupt count. > Either way, the generic IRQ code should deal with > duplicates without generating an oops. Agreed, this bug should be fixed either way.
