Subject: NOHZ: local_softirq_pending 20

Hello,

my kernel reported:

	NOHZ: local_softirq_pending 20

I cannot interpret it, but probably this is bad, because before
bc5393a6c9c0e70b4b43fb2fb63e3315e9a15c8f this used to BUG().

This happend while having a high load.  Up to now it only happend once
and I cannot reproduce it.

The machine is a cc7ucamry running v2.6.24-rc3-36-g4dd2d66[1].
Config and dmesg is available at

	http://www.modarm9.com/~ukleinek/20071123-local_softirq_pending/

Maybe the relevant source file is arch/arm/mach-ns9xxx/time-ns921x.c?
