Huh? Something's broken with your /proc/timer_stats. Either that, or
some application is polling the file at an insane rate. Were you
running powertop in the background at this time?

Nothing suspicious in your /proc/interrupts -- I assume the
'processor' module was still loaded at the time you took these
samples?

You can contact people responsible for the 'processor' module. Linux
get_maintainer.pl lists these emails for
drivers/acpi/processor_core.c:

Len Brown <lenb at kernel.org>
Bjorn Helgaas <bjorn.helgaas at hp.com>
Andrew Morton <akpm at linux-foundation.org>
Yinghai Lu <yinghai at kernel.org>
Alex Chiang <achiang at hp.com>
linux-acpi at vger.kernel.org
linux-kernel at vger.kernel.org

(Yeah, feel free to send an email to all recipients, that's how people
usually communicate on LKML)
