    sys/kern             kern_sig.c sys_process.c 
  MFC kern_sig.c 1.319 sys_process.c 1.134 to RELENG_5:
    Avoid kernel panic when attaching a process which may not be stopped
    by debugger, e.g process is dumping core. Only access p_xthread if
    P_STOPPED_TRACE is set, this means thread is ready to exchange signal
    with debugger, print a warning if P_STOPPED_TRACE is not set due to
    some bugs in other code, if there is.
    The patch has been tested by Anish Mistry mistry.7 at osu dot edu, and
    is slightly adjusted.
