I want to report that FreeBSD 9.1 (release/releng/stable) is having problem with ZFS and iRedMail. I was able to reproduce this on three machines including virtualbox but I don't have debugging skill to do this. 1) FreeBSD 9.1 (release/releng/stable) 2) ZFS in raid1 configuration. I created swap partition outside of ZFS and no change. 3) Installed iRedMail mail server from http://www.iredmail.org/ Before installing iRedMail, FreeBSD and ZFS are working normal. After I installed iRedMail and rebooted the server to load iRedMail configs. I rebooted the server again and it hangs after "All buffers synced". I did the above again with FreeBSD 9.0 and it work normal and reboot/shutdown without hang. This problem is easy to reproduce since I tried different configurations and disabled many modules including usb in kernel as well. FreeBSD 9.1 and iRedMail reboot/shutdown normal without ZFS. Scott
