How can i help in debugging this? I know only very little about core dumps, etc, so it would be cool if anyone of you guys can reproduce the lockup. Or tell me how to proceed.. flo - 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/
