If you and everybody else who is seeing this problem could provide
details about your configuration (output from cfgadm -lva, raidctl

of each disk in each zpool) that would help us sort through and find
any commonalities and hopefully a fix.
On a supermicro board, with 3 hw raid6 vdev joined in a single pool,
random hangs (<weekly) which required hardware reset, nothing on the logs.
symptoms: rpool fine, zfs status hangs on the other volume
all nfs shares stalled on all linux clients (local "share" -> nothing).
Attached the requested files on 2 machines having the same issue.
Two things here:
(1) your hba is a MegaRAID SAS ELP, which uses the mega_sas driver
not mpt, and
(2) If you've got nothing in the logs, then you need to do more
investigation to work out where the problem lies.
Since your system is not using mpt, you have a different problem.
