If you have a FreeNAS mini then you should check and consider to turn the watchdog function off in bios.
The mini's motherboard is ASRock C2750D4I and on bios version v2.90 it's by default turned off.
As I have encounter 2 failured motherboard it must have been set to on in bios before v2.90.
A motherboard with bios version 1.80 and BMC 00.14.00 only lasted 3 weeks before it stopped to boot. I only use freenas v9.3 due to the cifs performance problem.

From what I understand the official rumor is that this wearout only occurs on FreeNAS 9.10 and above.

But my experience is that you will encounter this problem if you have not disabled the watchdog in bios even on v9.3.
Last week I received a "repaired" board, and after a closer inspection the only part that is replaced is the small IC near the SATA connectors.
Its socket is the black one just bellow the throwhole in the upper left corner. -> http://www.asrockrack.com/Server/C2750D4I-1(L).jpg
The socket consist off 2 flaps that could unfold to remove the SOIC16.
The IC is a :
Windbond W25Q128FVFG.
Datasheet -> https://www.pjrc.com/teensy/W25Q128FV.pdf
It can be bought from ebay or aliexpress.

Will order and try out by my self. Is there someone out there who have done this process and is willing to share your experience ?
