My new TW/KDE system will not resume from hibernation but always reboots instead. This is new hardware and has never resumed since it was installed, the old hardware (also UEFI) used to resume just fine. Looking at the journal I can see:-

but the strange thing is that these happen on a normal boot as well as an attempt to resume which ends in a boot.
I have run memtest86 but no errors - this is a new system with a new install. My total memory is 16gb and my swap is 32gb (I plan to add another 16gb). Now I have no idea if these messages actually are a problem or not. The only messages relating to resume were:-

Anyone any ideas why this wont resume or how to move forwards with diagnosing it?
Stuart
I see the same thing on my laptop. What’s interesting is that I have been rolling with TW for a few months now and have always used Hybrid Sleep which works okay.
Just 2 days ago i switched to hibernation and when I wake up the laptop I only see a black screen on my laptop and external monitor with a mouse that does not move.
Ctrl+Alt+ any F key does nothing and I have to do a hard reset.
After the reboot my laptop screen is not working and the system moves in slow motion meaning when I click, the system responds about 2 seconds later until I get the laptop monitor back on and then it responds normally.

I also have a laptop running an i7 3537U also with TW/KDE and just checked and I also see those messages but the laptop boots just fine. I have also tried hibernation on it and resume works fine.

I have just updated this laptop today and re-tested hibernate resume and all worked OK. The journal shows these messages:-

so those messages are not stopping the resume.
So where to now debugging this on the desktop which will not resume?
Stuart
I’ll take a look at that but I don’t have any boot or shutdown issues per se, hibernate finishes and turns off the PC, boot boots normally with no apparent issues except it should have resumed!
I’ll scan the journal some more to try to find and indications there as to what might have gone wrong and see if anything turns up.
Stuart
There’s nothing untoward in those messages, the repeated “Marking nosave pages” is normal, it’s not necessary to save those memory pages.
So where to now debugging this on the desktop which will not resume?
In addition to the links that @karlmistelberger provided, you may find the following useful if you decide to investigate further.
“Debugging hibernation and suspend.” Debugging hibernation and suspend — The Linux Kernel documentation
Personally, I’ve always found hibernate/resume to be rather hit and miss, in the past kernel updates have caused a working system to fail and also vice versa. I’ve long gave up on it. Maybe some hardware is better suited than others, or perhaps it’s just down to the phase of the moon etc…
Just ran memtest and had errors, guess I’ll just keep using hybrid sleep and not hibernate.
