Anyway, this issue should be resolved from the root, > i.e., kern_resouce.c, if possible. But what to resolve there? I just want to always have a stable source "cpu ticks", and then everything else should just work? BTW, if someone comes up with a patch for more or less correct accounting when "cpu ticks" frequency is allowed to change, then I am all for it. But, IMO, it's just easier to use stable "cpu ticks". -- Andriy Gapon
