Post #1 of 1
I have an x86_64 2.6.27 kernel running on a Sandy Bridge machine.
why would irq0 have many many more interrupts than LOC?
/proc/interrupts currently shows 75573114 counts for irq0 on cpu 0 and
no counts on other cpus and between 2973587 and 4185923 counts for "LOC"
spread across all cpus including cpu0.
The following are enabled.
It almost seems like it's taking a timer interrupt on cpu0 for every
local timer interrupt on every cpu. Surely that's not design intent?
Any ideas on how to fix this?
