[SOLVED] Laptop suspend stopped working

Lenovo Thinkpad Yoga, used to work until yesterday's reboot (had not rebooted for a while).

Now when i close the lid the "suspend light" of the laptop flickers in a different way (more often) and when i open the lid X doesn't come back.

Having a look at journalctrl there's nothing obvious there.

Using Plasma 5.

Yesterday there was an update of device-mapper, no idea if it can be that, do you know if i can easily get the tar of the old version?

Any other idea of which package may be responsible of the regression? I guess the kernel?

Hero!

That's it, adding intel_iommu=off to my grub file made suspend work again smile

P.S: for those wondering where do you have to add the intel_iommu=off this is the line i added it to

linux   /boot/vmlinuz-linux root=UUID=2ed09345-2950-4ab6-8ffc-2b74ae35472a rw  quiet intel_iommu=off
