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.

Greetings
Christian
