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@us.ibm.com http://evms.sourceforge.net/ ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
