Hi, I've got a patch now up for review that breaks up TTY locking a little bit, with an eye primarily towards fixing the USB/TTY intersection that's been known to cause some problems in userland in the past; the pertinent change starts at usb_serial.c:633 in the below patch. Review is located here: https://reviews.freebsd.org/D24459 -- as far as I know, this is a complete and functional diff. I had ran it for a couple months on one of my 3d-printer-attached machines with no problems operating ucom under the new locking model and otherwise using the machine. Review and testing under tty-heavy and diverse workloads would be greatly appreciated. Please feel free to add yourself as a reviewer on phabricator. Thanks, kyle Evans
