On the laptop I see that the timer interrupt counter is incremented (though slower than HZ). This machine is running UP kernel. On my desktop I see this: CPU0 CPU1 0: 114 0 IO-APIC-edge timer 1: 1624 10771 IO-APIC-edge i8042 6: 3 0 IO-APIC-edge floppy 7: 0 0 IO-APIC-edge parport0 9: 0 0 IO-APIC-fasteoi acpi 12: 40111 184047 IO-APIC-edge i8042 16: 75624 998858 IO-APIC-fasteoi radeon@pci:0000:01:00.0, uhci_hcd:usb1 17: 0 0 IO-APIC-fasteoi uhci_hcd:usb4 18: 711 5487 IO-APIC-fasteoi ide1, libata, ehci_hcd:usb7, uhci_hcd:usb3 19: 617 2254 IO-APIC-fasteoi libata, uhci_hcd:usb2 20: 0 0 IO-APIC-fasteoi ehci_hcd:usb6, uhci_hcd:usb5 21: 2483869 0 IO-APIC-fasteoi eth0 22: 2 0 IO-APIC-fasteoi ohci1394 218: 28872 360643 PCI-MSI-edge HDA Intel 219: 32932 138196 PCI-MSI-edge libata NMI: 0 0 LOC: 2761191 2827539 ERR: 0 MIS: 0 Interrupt 0 is stuck at 114 (the number is consistent across reboots). I don't experience any problem, time is running fine. Still it's strange that the timer is doing nothing; maybe something other than the PIT is used for time keeping?
