I ran the Mar-15 version of 2.0.36 EMC, and the TkEmc UI.  It gave the
above message once or twice, but then came up.  The first time, it
hung the UI within 30 seconds.  I was able to kill it and get back to the
command prompt.  The second time, it ran for about 30-45 minutes, and
hung all of XFree86, and I had to reboot.  (I forgot to try telnet'ing into
it, to see if it was just X that was hung.  The RT section was still running
fine, but I don't know about the rest of Linux.)

Anyway, after that much trouble, I went back to 20-Dec-1999, since it
has been totally troublefree.  I tried out the backlash compensation, and
it seems to work, in the Mar-15 version.  I looked into the analog spindle
conrol, and it apears sections of code are missing, and the spindle speed
command won't get to the DACs.

I am running a servo system with a Servo-to-Go card.
