you should wait till Alan Cox releases a stable 2.4.14 or maybe 2.4.15 2.4.13-ac8 is too long out there and Linus made a vast merge from Alan's stuff i hope he'll finish 2.4.15 this week and then comes 2.5
back to MDK stuff why not give a try to vanila kernel when 2.4.15 is out Linus has merged ext3 intermezo zisofs mgag550-framebuffer and a lot of other things from Alan or we should stay with -ac any hints
