Subject: arm / kirkwood (openrd): cpu_idle
Date: Thu, 15 Oct 2009 13:52:41 +0200 [thread overview]
Message-ID: <200910151352.41991.dk-arm-linux@gmx.de> (raw)
Hi all,
we've discussed some days ago the cpu_idle issue on marvell kirkwood devices.
I got following output sometimes. I don't know if this is really a problem?
------------[ cut here ]------------
WARNING: at arch/arm/kernel/process.c:171 cpu_idle+0x74/0xbc()

I've tried to apply the patch Simon mentioned at
http://lists.infradead.org/pipermail/linux-arm-kernel/2009-October/001624.html
http://patchwork.kernel.org/patch/40871/
But it looks like that in rc4 something has changed so the patch didn't apply without errors.
And I don't know enough about this stuff to know what I'm doing :(
Any help would be appreciated!
Thanks in advance,
Dieter
