why would irq0 have many many more interrupts than LOC?
I have an x86_64 2.6.27 kernel running on a Sandy Bridge machine.
/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.
CONFIG_GENERIC_HARDIRQS=yCONFIG_PREEMPT_SOFTIRQS=yCONFIG_PREEMPT_HARDIRQS=yCONFIG_HIGH_RES_TIMERS=yCONFIG_HZ_1000=yCONFIG_HZ=1000
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?
