ok, that's forcedeth. Does that behavior go away if you revert the
change below, via patch -p0 -R ?

but in general, -rt will track IRQ cpu usage accurately, while mainline
does not measure it at all when in idle. So a frequent IRQ on mainline
might be using up similar amounts of of CPU time as well, but it's not
reported.

Ingo,
  GMail is being kranky. Can you please send the patch as a zipped attachment?
