title: What does "kernel tainted" mean?
body: <p>My OS is Fedora 17. Recently, kernel tainted warning "kernel bug at kernel/auditsc.c:1772!-abrt" occurs:
  This problem should not be reported (it is likely a known problem). A kernel problem occurred, but your kernel has been tainted (flags:GD). Kernel maintainers are unable to diagnose tainted reports.</p>
  
  <p>Then, I get the following:</p>
  
  <pre><code># cat /proc/sys/kernel/tainted
  128
  
  # dmesg | grep -i taint
  [ 8306.955523] Pid: 4511, comm: chrome Tainted: G      D      3.9.10-100.fc17.i686.PAE #1 Dell Inc. 
  [ 8307.366310] Pid: 4571, comm: chrome Tainted: G      D      3.9.10-100.fc17.i686.PAE #1 Dell Inc. 
  </code></pre>
  
  <p>It seems that the value "128" is much serious:
  128 – The system has died.</p>
  
  <p>How about this warning? Since chrome is flagged as the "Tainted" source, anybody also meet this matter? </p>
