So I've been monitoring local timer interrupts since the last reboot. Last reboot was on July 9 at 3:14 PM. I've been logging grep LOC /proc/interrupts every 10 seconds. Initially, both CPUs log about 1000 LOC interrupts per second. All of a sudden, CPU1 starts receving only 20 per second while CPU0 keeps getting its normal allotment of 1000 per second. This is the time where it happens: Thu Jul 10 12:13:59 PDT 2008: LOC: 75616236 75616322 Local timer interrupts Thu Jul 10 12:14:09 PDT 2008: LOC: 75626255 75626341 Local timer interrupts Thu Jul 10 12:14:19 PDT 2008: LOC: 75636275 75636360 Local timer interrupts Thu Jul 10 12:14:29 PDT 2008: LOC: 75646293 75646379 Local timer interrupts Thu Jul 10 12:14:39 PDT 2008: LOC: 75656312 75650462 Local timer interrupts Thu Jul 10 12:14:49 PDT 2008: LOC: 75666355 75650857 Local timer interrupts Thu Jul 10 12:14:59 PDT 2008: LOC: 75676378 75651251 Local timer interrupts Thu Jul 10 12:15:09 PDT 2008: LOC: 75686403 75651645 Local timer interrupts Thu Jul 10 12:15:19 PDT 2008: LOC: 75696420 75652039 Local timer interrupts Thu Jul 10 12:15:29 PDT 2008: LOC: 75706439 75652433 Local timer interrupts Thu Jul 10 12:15:39 PDT 2008: LOC: 75716476 75652827 Local timer interrupts Thu Jul 10 12:15:49 PDT 2008: LOC: 75726495 75653221 Local timer interrupts Thu Jul 10 12:15:59 PDT 2008: LOC: 75736514 75653615 Local timer interrupts Thu Jul 10 12:16:09 PDT 2008: LOC: 75746548 75654009 Local timer interrupts Thu Jul 10 12:16:19 PDT 2008: LOC: 75756573 75654403 Local timer interrupts Phil. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
