X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 20 Dec 2004 14:29:12 -0000 I have a current from yesterday evening and my serial (sio ... regular, builtin 16550A) hangs the machine when I use it. In particular, I'm running pilot-xfer. I believe that I use 115200 as my speed. The machine hangs hard with no messages on the console and no response anywhere. Another odd (possibly unreated) thing is that "tail -f" on a log file is exiting. I don't have a rule for it, but in my case it's reproducable where: process A is >& to the log file. A then spawns several 'B' processes using popen(). A loops to read output from all B using kqueue() and reports much of this to the logfile. When B's exit, tail -f on A's output exits. Odd. Now I just noticed that my tail -f log on a running "make -j4 buildworld >& log" exited as well. Double-odd.
