Hi Ingo, I'm getting this after building 2.6.14-rc4-rt6:

WARNING: /lib/modules/2.6.13-0.13.rrt.rhfc4.ccrmasmp/kernel/drivers/char/hangcheck-timer.ko needs unknown symbol do_monotonic_clock
WARNING: /lib/modules/2.6.13-0.13.rrt.rhfc4.ccrmasmp/kernel/drivers/input/gameport/gameport.ko needs unknown symbol i8253_lock
WARNING: /lib/modules/2.6.13-0.13.rrt.rhfc4.ccrmasmp/kernel/drivers/input/joystick/analog.ko needs unknown symbol i8253_lock

BTW, rt5 "settles" down after a while and I don't get timer problems
anymore (ie: fast key repeats and random screensaver activations). It
does right after a reboot (but I have not tried too many times).

thanks, applied this and the i8253.c one too.
