CURRENT: [USB] : GEOM_PART: da4 was automatically resized.

On every(!) USB drive which worked well with 11-CURRENT up to 11-BETA, I fail
to access with 12-CURRENT (12.0-CURRENT FreeBSD 12.0-CURRENT #14 r303475: Fri
Jul 29 11:59:11 CEST 2016) with the error shown below.

On USB flash drives I created myself, the suggested gpart command solved the
problem, but I can not do this with drives I was given by a vendor or supplier.

What is wrong?

Kind regards and thank you very much in advance,

O. Hartmann


On console, I get the report:

  Use `gpart commit da4` to save changes or `gpart undo da4` to revert them.
