FreeBSD 11.2-STABLE #0 r325575+fc3d65faae6(HEAD): Thu Dec 20 16:12:30 EST 2018     root@nemesis.tn.ixsystems.com:/freenas-releng-final/freenas/_BE/objs/freenas-releng-final/freenas/_BE/os/sys/FreeNAS.amd64  amd64

MB: ASUS P10S-E/4L (Intel® C236), 32G RAM ECC.
CPU: Intel(R) Xeon(R) CPU E3-1230 v5
Disks SATA, WD RE 2TB. 
ZFS, RAID Z2, 8 disks.

On the topic of the FreeNAS forum, I raised the issue of using an HDD in a ZFS pool using the Intel Sunrise Point AHCI Controller (Intel C236). If I start using the iscsi service (ctld - CAM Target Layer / iSCSI target daemon) then I can get chaotic mistakes from different disks.

Have errors with:

Restarting the server does not resolve the issue with "CAM status: ATA Status Error." Just turning off the server and turning the power on solves the problem.


When I start use external SAS controller "LSI 3008 in IT mode", now no any errors with disk. 
If start use again AHCI controller Intel Sunrise Point , CAM errors back.

Vendor support say that FreeBSD not in "ASUSTek Server Platform Supported OS List" - https://dlcdnets.asus.com/pub/ASUS/mb/socket1151/P10S-X/QVL/P10S_Series_OS_Support_List_2017.pdf

Does the Intel Sunrise Point AHCI Controller have any problems with FreeBSD?

We have a system running a ZFS mirror on Intel S1200SPO m/b with Sunrise Point AHCI with no problems. But not using iSCSI.

Is there a BIOS update to try?

If not use iSCSI , with SAMBA and zfs scrub all OK.

Latest BIOS, tested on two same m/b.
