 I'm running nvidia-drivers 375.66 with a GTX
 1070 on FreeBSD-Current
 
 This problem just started happening
 recently but, every so often my laptop
 screen will just blank out and then I
 have to power cycle to get the
 machine up and running again.
 
 It seems to be a problem with nvidia
 drivers acquiring duplicate lock. Any
 info on this?

... then Xorg will run happily twelve hours or so.  The lockups here happen usually
when too large or too many of number of tabs/ large web pages with complex CSS etc
are opened at a time.  
    So no help, just a 'me too'.
