>Well, if you're sure you need to use hibernation, I suggest you to upgrade
your kernel (v4.9 and newer will deal with it).*
>Your graphics card may require some proprietary drivers to successfully deal
with hibernation.*
*I don't suggest you to use versions newer than 4.9, cause you will have
problems with graphics. Gnome app installer is known to have problems with
rendering when used in systems with linux-libre v4.12 (as an example).
*Do not even try to use non-free drivers. $$ fglrx-driver 'FGLRX / AMD
Catalyst' for the ATI/AMD RadeonHD and FireGL graphics cards is recognized to
deal with hanging (as an example) $$. This way (which you don't want to go
for sure) requires installation and manual renewing of xorg.conf^^
^You will have to do this every time you wish to update your kernel, or when
you receive one.
^You will recognize noticeable downgrade performance as well..
You can get a newer version of linux-libre via APT repositories of you wish.\
