To reproduce it, I just did the following: 1) Boot a system with a Fixit image 2) Remove all gpart partitions 3) gpart the first disk (ad0) 4) Restored my data to the partitions from backups 5) Reboot 6) gmirror the ad0 disk And that's where I got kernel panic. gpart'ing the disk and the mirroring the partitions works just as fine, but not when you mirror the whole disk.
