If the reg ecc memory is broken, wouldn't it show on the console? I had this recently with one of my servers. Any attempts to write to the pool resulted in the writes stalling inifinitely on zio_wait. The FreeBSD 10 system eventually locked up propably because it was unable to flush any IO to the pool. The root pool was on a separate ssd mirror on a PCIe card and was unaffacted. Reflashing the IT firmware on the HBA did not help. Swapping the LSI HBA fully resolved the issue. I wasted lots of time before I finally swapped the controller partly because I did not have spares flying around.
