If this is less than 100 then it disables the IRQ. So I suspect one of these devices is misbehaving, or its driver is not handling interrupts correctly. Is 'pppp0' actually an Ethernet device that you're using for PPPoE? If so, what model of network card is it? > 5: 0 XT-PIC-XT ehci_hcd:usb1, lan0 > 7: 6959 XT-PIC-XT lan1 > 8: 2 XT-PIC-XT rtc0 > 9: 0 XT-PIC-XT acpi > 11: 37697 XT-PIC-XT ide2, ide3, ohci_hcd:usb2, lan2 > 14: 0 XT-PIC-XT ide0 > NMI: 0 Non-maskable interrupts > TRM: 0 Thermal event interrupts > MCE: 0 Machine check exceptions > MCP: 13 Machine check polls > ERR: 2 >=20 > How can i assigned IRQs during Boot? [...] They are assigned by the BIOS. You may be able to configure this in BIOS setup.
