I get a lot of

WARNING: /lib/modules/2.6.17-hrt-dyntick1/kernel/sound/pci/ac97/snd-ac97-codec.ko needs unknown symbol msecs_to_jiffies
WARNING: /lib/modules/2.6.17-hrt-dyntick1/kernel/drivers/net/skge.ko needs unknown symbol jiffies_to_msecs
WARNING: /lib/modules/2.6.17-hrt-dyntick1/kernel/drivers/cpufreq/cpufreq_ondemand.ko needs unknown symbol jiffies_to_usecs
etc...

warnings.

Here is fix small fix.

Regards,
Michal
