in combination with dnf history undo
1. check your /etc/default/grub: GRUB_CMDLINE_LINUX=" resume=/dev/sdXN rhgb
quiet"
2. run all three pm-is-supported [{--suspend | --hibernate | --suspend-hybrid}] now (echo
$?)
3. dnf history undo ( does this work for kernels too ?) up to the date where your system
hibernates/suspends
4. single re-install the packages one by one and test between each install again with
pm-is-supported
P.S.
I don't know why pm-utils isn't packaged for Fedora 25, maybe redeemed by another
package ???
