I create the devices using this link: http://www.mattiasholm.com/node/33 I tried 3 different hard drives (Seagate 2x80GB and 1x400GB SATA2) which are fine on a physical machine. I also ran Seatool many hours on all of them without errors. I can partiton the disks and create a few files/directories on it. But as soon as I copy a larger number of files to those disks (tried with MBR and GPT) the VM reboots *instantly* (I tried cp, dump/restore and rsync). No "Rebooting within 15 seconds", just *snap*. I think I can see an panic but I'm not sure, it's too fast. (as far as I can see most of the times the data on the first UFS slice (and only the first UFS slice!) of the partition gets *severly* corrupted, most of the time all that is left are a few files within lost+found. Sometimes all the labels are gone but are recoverable using bsdlabel -R) The problem is that /var/crash remains empty. What can I do to create a backtrace to open a PR? Thanks, Helmut
