Willem, I can only guess, but... Is AHCI enabled in the bios? If you are not using 'fake-raid' for any disks, you should [depending on FreeBSD version, HBA, etc.] probably enable AHCI. Some servers actually come with SATA set in IDE mode. And if you are using zfs, the controller optimally should not be RAID at all. And if you have AHCI enabled already, try disabling it (losing hot swapping ability, and some performance). What version of FreeBSD are you using? I had a terrible experience with ZFS on FreeBSD 8.2 release, and 8.2-stable-April2011. I would recommend upgrading to the latest 8-stable with cvsup. This thread seems related: http://forums.freebsd.org/showthread.php?t=24189 The guy was using 8.2 release, and he downgraded to an old version of the driver to fix, saying that a patch also existed in 8-stable that fixes the problem. Are you using an expander? What HBA / hard disk controller are you using?
