Hi Uwe I triple checked. > I think targetinstall should ask about the changed config items. It only asks one way, when going from an upatched kernel to an patched one. Since i was coming from an preempt rt kernel to an unpatched one no questions where asked (probably since all settings where still in place as i wasn't using the preempt rt feature with the preempt rt patched kernel source aka "Low latency desktop") > check if ${PROJECT_DIR}/${PLATFORMNAME}/build/linux-3.0/ (or similar) > really has the rt patch applied. (e.g. is there a localversion-rt file?) Yes, one version has rt7 appended the other not. But i think the regression when going from 3.0-rt7 to 3.0.1-rt8 with CONFIG_PREEMPT_RTB is more worthwhile to discuss. Which i detailed in the other mail.
