--- Comment #1 from Konstantin Belousov <kib at FreeBSD.org> ---
Can you provide the minimal test case which reproduces this issue ?  It might
depend on the kernel configuration.

With the core dump you get, load it into kgdb and print out the trap frame by
doing
  frame 7
  p/x *frame

Also I am attaching a patch which covers code paths which might cause that
effect, from reading of the code.
