Similar to 179107 and 179109 (though didn't try fix from 179109 yet). When I detach mounted USB memory stick, keyboard dies. The same happens when I detach "bad" memory stick, that I can't mount on my FreeBSD-9.3-RELEASE.
Please: is this reproducible with FreeBSD 13.0-RELEASE? If so: what's the file system of the improperly detached device?
