Nes. Let denote "C" compilation with TC, "1" a full crash (i.e. no reaction at all), "0" Numlock and Ctrl-Alt-Del work, "c" cold boot, "w" warm boot. Then I found the wollowing pattern: C 1 c 0 w 0 w... C 1 c 0 w 0 w It seems that it depends on what is in memory. It crashed completely when I had used TC first.
