Bug#946242: fatal: privsep_preauth: preauth child terminated by signal 31

[crunch <bob@mroczka.com>]

Package: openssh-server
Version: 1:7.9p1-10+deb10u1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation? apt upgrade lead to openssh-server
   * being unusable.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?  bug #941663 supposedly fixed this issue in the
     version I upgraded to but the symptom remains. Also tried
     installing 8.1 version but that did not fix the issue either. I am
     running a 3.16 kernel because a 4.x kernel is not supported on my 
     hardware (AMD Geode LX processor).
   * What was the outcome of this action? no change
   * What outcome did you expect instead? to login
