    sys/kern             kern_lock.c 
  Log:
  Merge kern_lock.c:1.94, 1.95 from HEAD to RELENG_5:
  
    In lockstatus(), don't lock and unlock the interlock when testing the
    sleep lock status while kdb_active, or we risk contending with the
    mutex on another CPU, resulting in a panic when using "show
    lockedvnods" while in DDB.
