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.

Dave.
