Thanks. This helps debugging. The relevant log line:
/usr/lib/dracut/modules.d/74resume/module-setup.sh@25(check): return 255
This means you hit this code path:
if grep -rqsE '(^| )resume=' /proc/cmdline /etc/kernel/cmdline
/usr/lib/kernel/cmdline; then
# hibernation support requested on kernel command line
return 0
else
# resume= not set on kernel command line
if [[ -f /sys/power/resume ]]; then
if [[ "$(< /sys/power/resume)" == "0:0" ]]; then
# hibernation supported by the kernel, but not enabled
return 255
Can you test following with a fresh system:
1. Make sure system is supported the power state
user@localhost:~$ cat /sys/power/state
freeze mem disk
2. Configured swap partition and populated the resume kernel boot
parameter resume=/dev/<swap partition> and update the grub
3. Reboot the system
4. Regenerate the initrd with debug log and no dracut config changes.
Does that include the resume module? If not, please provide the debug
log for that case as well.
After the reboot you should hit the "hibernation support requested on
kernel command line" case or /sys/power/resume should contain something
else than "0:0".
