After a few minutes of operation, sound began repeating and the computer spontaneously rebooted. All I have in the logs is: *Jun 20 22:31:46 nexus root: ZFS: checksum mismatch, zpool=mypool path=/dev/ad1s2 offset=47253578752 size=3072* Jun 20 22:32:53 nexus syslogd: kernel boot file is /boot/kernel/kernel Jun 20 22:32:53 nexus kernel: Copyright (c) 1992-2007 The FreeBSD Project.
