Lo and behold, after following Mark Hahn's advice of adding "noapic" to lilo append, 2.2 is booting without any complaints! He actually suggested it for 2.4 and after having successfully testing it on 2.2, I'm now running 2.4 with noapic, hoping it will magically make my lockup problems go away just as it fixed 2.2. When 2.4 dies on me next time (after thinking "this will surely fix it!" after every potential fix and getting disappointed, I've stopped using "if"), I will try 2.2. The sad thing about that is that there's no Hyperthreading but if it's stable, it's most definitely worth the performance penalty. > After boot disable screen blanking with "setterm -blank 0" I'm using echo -e "\33[9;0]" > /dev/console to disable screen-blanking on all my servers. There's something about a monitor suddenly going blank that gets my heart pumping...
