ttyS2 should be the Embedded Remote Access controller, which appears to
the OS as a standard serial port.  Problem is, OMSA 3.5 diags can't tell
the difference between a normal serial port and an ERA, so it tries to
run inappropriate tests against it, and fails.  This is a known issue,
and the diags team is trying to figure out the best way to handle it in
future OMSA releases.  It's a harmless error though.
