If 15.5 supports it, that's fine, but I have been told it isn't: <https://lists.opensuse.org/archives/list/users@lists.opensuse.org/message/LJBW2M24IVP5NN7ROACLRI4V7DZ7IZ56/> Thank you very much for the information about hibernation. I'll add some information: There is a setting in the BIOS aka UEFI that says: Sleep State: Windows and Linux vs Linux S3 hibernation With the default first choice, the machine does not reach hibernation: Mar 29 20:47:06 Laicolasse kernel: Wakeup pending. Abort CPU freeze. Using the second option, the machine indeed does panic, but before powering off during hibernation. I have logs: <https://paste.opensuse.org/pastes/46f774d01960> Do you want this information in another bug, or is it known?
