[Debian-ha-maintainers] Bug#965253: drbd-utils: drbd not working after kernel upgrade >5.3.x

[Denis Witt]

Package: drbd-utils
Version: 9.5.0-1
Severity: important

Dear Maintainer,

drbd-utils are not working with an kernel >5.3.x making it impossible to use DRBD at all.

   * What led up to the situation?
   
   Upgrade to linux 5.4.44-2
   
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     
   Installed the new kernel, rebooted, drbd didn't start anymore.
   Downgrading to stock kernel => drbd is working again.
   
   The same issue seems to be fixed in Ubuntu already:
