Yep! Once in a while, the EMC leaves some left overs in mbuff and can't
shut it down. I sent Henkka a note on this and I think that it is included
in the FAQ at linuxcnc.org/handbook

Easiest solution, (I don't like it 'cause it's the MS way is to reboot).
Next easiest way is to cd to /usr/src/rtlinux/mbuff and issue a "make
test" command. After a bit your terminal will settle down with no prompt
so press <control>c and then enter

./mbuff_dealloc emcmotStruct

and enter. Repeat this until it returns a -1 condition and then

rmmod mbuff

and it should go away.
