r22412 seems broken as well.

I *think* this happened at rev 22305, but it's getting late, and I wasn't doing rebuilds every time.

Same problem on a backfire@22752 on soekris 4501

Simply disabling the crashlog removed the warning. I've attached a patch to do this for RDC, but quite possibly it should be applied to the generic 2.6.32 config instead. I had a brief look but the crashlog code is a closed book to me, and I've no idea why it triggers the warning.
