Package: powertop
Version: 2.10-1
Severity: grave
Justification: renders package unusable
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Running `powertop` or `powertop --auto-tune`
* What was the outcome of this action?
powertop gets terminated with SIGKILL (according to stack trace)
* What outcome did you expect instead?
powertop should run normally
It worked fine on the previous unstable kernel (4.19.0-5 if I'm not mistaken).
Below is the output from `dmesg`:

Is this a kernel bug, or a powertop bug? Or is there something horribly wrong
