I don't think apache2 uses nonlinear. there was an smp race fix in 2.6.5-aa4, so you may want to try again with 2.6.5-aa5 (latest) just in case this was mm corruption triggered by the race. Are you using threading with apache2? Such a race could trigger only with threads. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
