Thank you for suggestions. But how to do it? The patch already contains:

if (console_loglevel >= CONSOLE_LOGLEVEL_DEBUG)
      early_printk("Early printk is initialized\n");

But I've just noticesed that it does not print anything, because
console_loglevel can be CONSOLE_LOGLEVEL_DEBUG
only after parse_early_params too :) How to better be with it? To remove
if clause and just leave early_printk or something else?

Or you meant something else about patch for testing?
