Hi, I have an Ubuntu 18.04 with kernel 4.20.10 (compiled manually with default Ubuntu options but changing the processor type to Xeon) I tested the version 2.9 and the latest code from git (tag 2.10): # git log e8765b5 (HEAD -> master, tag: v2.10, origin/master, origin/HEAD) src/wakeup/wakeup.h: Fix a minor issue in the wakeup.h file And I got a coredump when I run it normally and with --auto-tune (I dont have the coredump with --debug). The same coredump on normal run and with --auto-autotune. See attached the output of gdb (bt, registers, ...) and the coredump. Let me know if I can do anything else to help you to fix the bug, I'm not C developer but I have a minimal knowledge about compiling code, patching, debug, ... Regards, Pablo

Hi, Now compiling the latest kernel, I'll provide you more feedback tomorrow. Attached my kernel config. Not sure if it is a problem with the kernel or hardware... I'll check it tomorrow too by running the latest stable kernel provided by Ubuntu. Regarding powertop version: I tested with latest version from git (tag: v2.10) and powertop 2.9 from Ubuntu 18.10 package. Same coredump when running powertop without args and with --auto-tune.
