2. Go to hibernate with either of the following commands :

   # echo disk > /sys/power/state
3. if you try with the second command try to wake up the platform pushing any key / if you try with the first command wait 60 seconds

dmesg.log, which containg the log when the platforms try to enter to S4 state

Additional information
===========================================
in order to send the platform to S3 (suspend) / S4 (hibernate) you have to enable it in the grub in the following way :

1. $ dmesg | grep -i "swap on"  # to know where is your swap partition

example : /dev/mapper/fedora-swap

2. add the following parameter in the file /etc/default/grub

resume=/dev/mapper/fedora-swap

add it at the end of the line : GRUB_CMDLINE_LINUX=

3. update the grub : grub2-mkconfig -o /boot/grub2/grub.cfg

this a common issue in Fedora, for more detail information please read the following article : https://fedoraproject.org/wiki/Common_F24_bugs#Hibernation_doesn.27t_work_from_a_standard_install


Please correct me if i am placing this issue in the wrong component, thanks

Hi,

Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org.

To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default).

Sorry about the noise!
