Hi
You should be able to see the core dump and more information via;
zypper in systemd-coredump
coredumpctl list
output of coredumpctl list is :
No coredumps found
Hi
Do you get more info just running the command?
/usr/sbin/powertop --auto-tune
The output from /usr/sbin/powertop --auto-tune is :

Hi
So how much memory does the system have? Before you run powertop, how
much is free (free -kh)?
Can you try;
/usr/sbin/powertop --calibrate --debug

on Tumbleweed 4.20.7-1 powertops 2.10 it works
I wrote to developers of PowerTop and I have an e-mail with their explanation :
I can confirm that works fine on kernel 4.20.7 and 4.20.11, but not on kernel 4.20.10
So, it seems a problem with powertop running on kernel 4.20.10? (not tested 4.20.9 nor 4.20.8 as I did not compiled it)
The issue is with kernel 4.20.10.

Hi
Ahh ok, still on 4.20.7 here… you could probably raise a bug, but
you might have to look at bisecting the kernel to figure out what is
what.
