There is a skew in the loadaverage due to a commit introduced in 2.6.36:
commit 74f5187ac873042f502227701ed1727e7c5fbfa9
Author: Peter Zijlstra <a.p.zijls...@chello.nl> 2010-04-22 21:50:19
Committer: Ingo Molnar <mi...@elte.hu> 2010-04-23 11:02:02
sched: Cure load average vs NO_HZ woes
Check https://bugzilla.kernel.org/show_bug.cgi?id=16525 and the
referenced threads for more details on that.
It is not clear to me, if that skew is accompanied by any harmful symptoms
though...
Regards,
Flo
p.s.: for convenience, I post the backtrace mentioned in comment #12:
