--- Comment #104 from George Mitchell <george@m5p.com> ---
Same problem here with 13.1-RELEASE-p2, though HIGHLY intermittent (roughly
once a month, and, oddly, within three minutes of booting up or else never). 
Also, it's a long-standing problem on this board, going back at least to FBSD
11.  Using the port fixes the problem, I think.  So far.  The port should
probably be more widely advertised.  Is there a copyright problem with adopting
the port into base?
