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!

Regards,
Yunseong
