Symptoms

Oracle Exalytics X3-4 server with Patchset 4 (PS4) installed and two OVM 3.2.7 servers suddenly rebooted itself for no apparent reason. This machine had been up and running fine for a few months, but was taken down for hardware battery replacement.
After battery replacement, the server was successfully restarted and ran fine for a few days before suddenly rebooting today. 

The /var/log/messages file shows many messages like:

These messages match the known issue described in <Document 1904921.1> - Exalytics /var/log/messages Shows Smartd Error: "smartd[10687]: Device: /dev/sdd [SAT]...Offline uncorrectable sectors", but according to the note, the issue does not occur in Patchset 4 (PS4).  This machine is running PS4.
