BTW, I tried to reproduce the error with issuing the same command -- didn't
work.
Second thing: I was trying to reproduce the system lock error I told about
earlier (with no success). When I did 'make -j zImage' and tried to exit
X-windows during that (alt-ctrl-f1) the system locked up completely
(didn't listen to keyboard or network).
