    Hi,

    I'd upgrade today kernel to last experimental version :
"linux-image-4.14.0-rc7-amd64"

    Issue is the same, black screen on hibernate exit, but computer is
still remotely reachable through ssh.

    I attach 4.14 journald logs.

    According to https://01.org/linuxgraphics/documentation/how-get-gpu-error-state , I try to collect GPU error:

# cat /sys/class/drm/card0/error
No error state collected


    For information, few months/years ago, while this computer was into Testing/Stretch (not Buster),
hibernate was working fine. So hibernate functionality was lost before 4.9 kernel upgrade.

    Thanks for your help.

    Best regards,

                                                Olivier
