--------------------------------------------------

             Summary: DAHDI does not compile on kernels >= 5.6
                 Key: DAHLIN-390
                 URL: https://issues.asterisk.org/jira/browse/DAHLIN-390
             Project: DAHDI-Linux
          Issue Type: Bug
      Security Level: None
          Components: General
    Affects Versions: 3.1.0
         Environment: Ubuntu 20.04, do apt-get update && apt-get dist-upgrade so you end up with the latest kernel which is 5.8 at the time of this writing
            Reporter: Juan Carlos Castro y Castro

            Severity: Critical
