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?
No I wasn't running anything in the background, really stange indeed...
Nothing suspicious in your /proc/interrupts -- I assume the
'processor' module was still loaded at the time you took these
samples?
right
I have already compiled a minimal 2.6.31 and a 2.6.32 kernel and the problem
seems to be a regression introduced in the former. So I'm trying to find
time for a git bisection... Any other ideas?
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@xxxxxxxxxx>
Bjorn Helgaas <bjorn.helgaas@xxxxxx>
Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Yinghai Lu <yinghai@xxxxxxxxxx>
Alex Chiang <achiang@xxxxxx>
linux-acpi@xxxxxxxxxxxxxxx
linux-kernel@xxxxxxxxxxxxxxx
(Yeah, feel free to send an email to all recipients, that's how people
usually communicate on LKML)
Thanks for the tips, they are very useful!
