I really don't want that. This was purposely done to be mutually exclusive. The reason I added this in the first place, is because too much enabled will render the system useless if printk() is used.
After boot up, if I had enabled all debug events and then I were to disable the acpi tracepoint, it will likely render the system useless again if it were to switch over to printk.
