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. Apr 24 11:25:55 knew kernel: (da7:mps1:0:17:0): READ(10).
