title: Getting “Code: Bad RIP Value” kernel panic when trying to boot up after reboot
body: <p><strong>Description of problem:</strong></p>
  <blockquote>
  <p>I have installed Debian 10 Buster. EA01A NEC M2M LTE Dongle is attached to Device and configured for internet access.
  I have scheduled a reboot everyday at 1 AM. and I have noticed some times after reboot the system does not boot up properly. And shows “Code: Bad RIP value”.
  This issue does not always occur and is not able to be reproduced yet.</p>

  Thank you so much in advance for your help.</p>
