New Revision: 202821
URL: http://svn.freebsd.org/changeset/base/202821

Log:
  Fix a long standing ASF heartbeat sending bug. The initial
  implementation of heartbeat interval was 2 but there was typo which
  caused the heartbeat is sent approximately every 5 seconds. This
  caused unintended controller reset by firmware because firmware
  thought OS was crashed.
