I found the problem. This is bug #585786. Please merge/close as you find appropriate.
I still had dmsetup from lenny. After upgrading dmsetup to testing (version 2:1.02.48-1, matching libdevmapper), everything works again. Thanks for your help. Bjørn -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
