Hi Doru,
I have gone through the attached logs and observed some prints about
hibernation failure.
--
[ 3.788370] PM: Starting manual resume from disk
[ 3.788375] PM: Hibernation image partition 8:9 present
[ 3.788377] PM: Looking for hibernation image.
[ 3.788638] PM: Image not found (code -22)
[ 3.788640] PM: Hibernation image not present or could not be loaded.

Is it the problem you are trying to point ? Please clarify.
Is it regression from 4.14.20 to 4.9.82 due to megaraid_sas driver backporting
?
Thanks,
Sumit
