Thanks for the help.  The strnage thing is that after June 6, 18:00, this
message avc:  denied  { ioctl }... suddenly does not show up any more (up to
now, June 8, 9am).  If it shows up again, I will do the above.  Now, I am just
curious what happened.  I did not change the policy in these two days, did not
change any system setting either.  What does the error message mean?  What is
