Bug ID 22815570
Issue: The physical link between the host server and the Oracle ILOM service processor (SP) is the USB communication class ECM (usbecm) driver. After the first post-installation boot, the usbecm driver causes a network timeout, which causes the link between the host and SP to fail.
Affected operating system: Oracle Solaris 11.3
Workaround: Reboot the server.
