#7 (hopefully) solved it for me. Latest Ubuntu-20.4.2 update supplied me with kernel 5.8.0-48. There the problem existed.
Going after #7's suggestion, I installed 5.12.0-051200rc6drmtip20210410-generic and now the problem did not occour for 20+ hours of operating "dangerous" applications which previously were sufficient to trigger the problem (LibreOffice, generic Java (office) applications, wine with simple games).
