title: Where does output of print in kernel go?
body: <p>I am debugging a driver for linux (specifically ubuntu server 9.04), and there are several printf statements in the code.</p>
  
  <p>Where can I view the output of these statements?</p>
  
  <p>EDIT1: What i'm trying to do is write to kernel using the proc file-system.
  The print code is</p>
  
  <pre><code>static int proc_fractel_config_write(struct file *file, const char *argbuf, unsigned long count, void *data)
  {
      printk(KERN_DEBUG "writing fractel config\n");
      ...
  </code></pre>
  
  <p>In kern.log, I see the following message when i try to overwrite the file /proc/net/madwifi/ath1/fractel_config (with varying time of course).</p>
  
  <pre><code>[ 8671.924873] proc write 
  [ 8671.924919] 
  </code></pre>
  
  <p>Any explainations?</p>
