Your shared file is missing important information for approaching this issue. We need the *currently loaded kernel module* and *kernel log*. As I've mentioned from previous mail thread: $ lsmod $ journalctl -b 0 > journal-fresh-boot.log $ journalctl -kf > hibernate-watch.log 2>&1 & After reboot, Can you attach those log file? Thanks!
