Subject: When is save to print console messages?

Hi,

I want to use print some trace messages to the console in the kernel
setup/init stages. But I don't know what is the earliest time when safe
to do that.  Sould be somewhere after decompress_kernel() invocation?

And, when should I use putstr() and when to use printk()? Thans.

I can't go back to yesterday - because I was a different person then.
