Hibernate writes image, then hangs

I have a new EVO GRAM laptop with Fedora 36  installed. I use it when traveling when working on a RT broadcast playout server.

One of the unsolved problems is hibernate. It appears I have solved nearly everything with the following changes:

• disable secure boot

• add

  "[...] resume=PARTUUID=<swap-partition-uuid>"

  to GRUB_CMDLINE_LINUX in /etc/default/grub

• instantiate it with grub2-mkconfig -o /boot/grub2/grub.cfg

• create swap partition, add this to /etc/fstab for mounting: PARTUUID=<swap-partition-uuid>  none swap defaults 0 0

The hibernate process of writing to disk works, but hangs right after it saves the system image. Adding

no_console_suspend ignore_loglevel

to GRUB_CMDLINE_LINUX produces the console output below.

At this point the power led on the keyboard is on, the screen is on and the system is unresponsive except to pressing the power button for 5 seconds to shut down the system. Powering it up correctly restores the system from hibernation.

Anyone know the cause of the hang?

Re: Hibernate writes image, then hangs

Hello there

I have exactly the same problem on Arch since a kernel update (I think it was 5.17).

Before that, everything was working (suspending to an encrypted swap partition).

Now, it writes to the disk then hangs like you.

Only solution is to long press power button.

After that, on reboot, the disk content is restored to RAM and everything is fine.
