Distribution: debian unstable Hardware Environment: AMD Athlon Thunderbird, nforce2-Chipset Software Environment: Problem Description: The irq21 of this nforce2-board is triggered pretty often... 21: 1106804524 IO-APIC-level ehci_hcd 10 seconds later: 21: 1108150969 IO-APIC-level ehci_hcd I didn't even use any USB-device in that period. Since my systems is running pretty stable this issue (?) is not very important to me. But I have been getting curious, if this behaviour is simply normal or a bug or whatever... It happened with earlier kernel versions too... Steps to reproduce: I just booted... system infos: cat /proc/interrupts: CPU0 0: 57170836 IO-APIC-edge timer 1: 54302 IO-APIC-edge i8042 7: 0 IO-APIC-edge parport0 8: 4 IO-APIC-edge rtc 9: 0 IO-APIC-level acpi 12: 534130 IO-APIC-edge i8042 14: 237068 IO-APIC-edge ide0 15: 214 IO-APIC-edge ide1 16: 51349 IO-APIC-level ide2, saa7134[0] 17: 191473 IO-APIC-level CMI8738 19: 5059181 IO-APIC-level nvidia 20: 8242106 IO-APIC-level ohci_hcd, eth0 21: 1108150969 IO-APIC-level ehci_hcd 22: 88 IO-APIC-level ohci_hcd NMI: 20236 LOC: 56976096 ERR: 0 MIS: 0
