With that If enough RAM is chopped off users will notice. They tend to complain when they miss RAM. I don't like panic very much because for many users it will be a show stopper (even when they are not blessed with "quiet" boots like some distributions do) The message in dmesg could be also emphasized a bit with a little ASCII art (but no tag in there) The problem I'm more worried about is if the system will be really stable --- could it be that the memory controller is still misconfigured and cause other stability issues? (we've had such cases in the past). Also I'm not sure we can handle the case of the MTRR wrong not at the end of memory but at the hole sanely. -Andi - 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/
