Hi Julien,
I have applied the given patches sent by amazon on mainline linux
4.17.4 branch commit bdeb8f5.
Even after applying given patches the crash as seen below is
encountered in domU while trying to hibernate to disk usin xen-4.10.

Also, one more observation I have had is that hibernation image
creation does not crash for linux mainline version upto v4.7.10 but
not for later versions.
Although for v4.7.10 after resume and getting console, commands like
sync or ps do not give any output and hangs till I give kill command
(Ctrl + C).
Given below is the log for attempting hibernation with linux mainline
v4.7.10 (commit id b3afc45)
