Freezes after Lock Screen or switched off Monitors

[Salve Mundus <SalveMundus@gmx.de>]

Hello,

I wanted to report the freezes I observe with debian testing.  I
already mocked it up by choosing "bugs.debian.org" as the responsible
in the Reportbug GUI:

 * https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892982


Now I want to do report these freezes in the right way and I'm
wondering, which package to select.  I get errors logged by amdgpu and
gnome-shell in "kern.log".  What package or which bug category should I
choose to report this?



Kind Regards
  Hermann
