I don't have the image because no disks are mounted at that stage and the swap slice is not attached. But I can issue more specific DDB commands to narrow it down, just say what you need in detail. BTW, the machine have 2 DVD both are attached to Marvell IDE plain ATA interface, they always works before. Are you sure that something holding the lock? 'show lock' shows absolutely nothing, it is empty. -- http://ache.vniz.net/Received on Wed Jun 22 2011 - 02:13:28 UTC
