Is there a specific scenario that causes the kernel to oops if an MD device is made of DM devices? EVMS has been using this kind of configuration for a couple years, and we've never noticed a problem with it. Also, syrius mentioned on IRC that this problem only started occurring with -ac10, and that -ac8 worked fine. I'm checking out the diffs between those two versions to see what else might have changed. -- Kevin Corry kevcorry@xxxxxxxxxx http://evms.sourceforge.net/ - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
