| |
In kernels 102, 103, and 104-1 (SMP) I've been getting these messages repeatedly.
/proc/interrupts: CPU0 CPU1 0: 41574 111 XT-PIC timer 1: 1570 1638 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 3: 8014 5914 IO-APIC-edge serial 4: 6 0 IO-APIC-edge serial 5: 14654 9534 IO-APIC-edge busmouse 8: 1 0 IO-APIC-edge rtc 10: 0 2 IO-APIC-edge soundblaster 12: 82 43 IO-APIC-edge 3c509 13: 1 0 XT-PIC fpu 19: 9609 9607 IO-APIC-level aic7xxx NMI: 0 IPI: 0
Before this, I never got any timer interrupts on CPU1, so I assume those are the interrupts causing this message. They climb over time, but at a much slower rate than CPU0.
It doesn't seem to cause any problems, but it does get rather annoying.
The relevant boot info is (under 103):
