More of the pasted output is also at https://gist.github.com/dlangille/1fa3135334089c6603e2ec5da946d9ae <https://gist.github.com/dlangille/1fa3135334089c6603e2ec5da946d9ae> and added smartctl output.

I have a FreeBSD 10.2-RELEASE-p14 box in which there is an LSI SAS2008 card.  It's running a zfs root system.

This morning the system was unresponsive via ssh. Attempts to log in at the console did not yield a password prompt.

A power cycle brought the system online.  Inspecting /var/log/messages, I found about 63,000 entries similar to those which appear below.

zpool status of all are OK. A scrub is in progress for one pool (since before this issue arose). da7 is in that pool.

Is this a cabling issue?  The drive is a SATA device (smartctl output in the URL above).  Anyone familiar with these errors?
