title: AWC EC2 Amazon Linux 2 Instances failed to boot after applying os updates
body: <p>Yesterday we lost contact with 10 identically configured servers, after some investigation the conclusion was that a reboot after security updates had failed.</p>
  <p>We have so far not been able to get any of the servers back online, but were lucky enough to be able to reinstall the instances without data loss.</p>
  <p>I will paste the console log below, can anyone help me determine the root cause and perhaps give me some advice on if there is a better way to configure the server to make recovery easier (like getting past the &quot;Press Enter to continue.&quot; prompt, that it seems to hang in).</p>
  <p>The full log is too big for SO, so I put it on <a href="https://pastebin.pl/view/d6829d61" rel="nofollow noreferrer">pastebin</a> and pasted a redacted version below. I have removed the escape sequences that colorize the output and removed some double new lines, but besides that it is complete.</p>
