I had some problems like this using 2.4.17 on a PIIX3 board (don't know the board type). The problems disappeared after switching to 2.4.19. Unforunately I had to change the processor and processor fan about the same time.
I tend to believe that this problem was related to CPU temperature not to kernel bugs. I don't have any means of measuring CPU temperature on this board. But the old CPU certainly burnt out, because the fan was not working too well ;-(((
