Try as I might I've been unable to get a coredump so I can investigate further. Minimum required to reproduce the error here is to install 8.2-RC1 from CD and on reboot, drop to the boot loader prompt and type: load geom_mirror boot da0 contains all of the installed files, da1 was to be a mirror of da0 so was left alone, and da2 was created as one big partition. I first noticed this when I installed 8.1-RC1 and then ran the following commands after rebooting from the initial install: sysctl kern.geom.debugflags=17 gmirror label -vb round-robin gm0 /dev/da0 echo 'geom_mirror_load="YES"' >> /boot/loader.conf sed -i.bak -e's,da0,mirror/gm0,g' /etc/fstab reboot When the box came back up I got a panic. I've tried various combos to figure out what the minimum was to reproduce this. I've verified that 8.0-RELEASE, and 8.1-RELEASE don't exhibit this same behavior. If further info is required, please let me know. -steve
