I would treat all your traces with suspicion, the base data is very unreliable. Try to reproduce with current modules, instead of modules that have changed since the oops. BTW, do not specify -O unless you have a good reason to ignore objects, which you don't. You should supply a system map with -m instead of suppressing it with -M. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
