When I activate sleep mode, my laptop gets stuck and hangs. I have to switch it off and it takes a long time to open with the power switch.

I'm using kubuntu 21.10 my kernel ver:-5.13.0-28-generic

Kernel: 5.13.0-28-generic x86_64 bits: 64 compiler: gcc v: 11.2.0 Desktop: KDE Plasma 5.22.5

System msi modern amd Display: x11 server: X.Org 1.20.13 driver: loaded: amdgpu,ati unloaded: fbdev,modesetting,vesa
resolution: 1920x1080~60Hz

it's normal, when your laptop is in hibernating mode, it saves sessions on ram or on the hard drive

here are the two main causes:

1- you don't have much ram
2- you have an HDD

Same here. General instability with this kernel update. Experiencing freezes while in use + just like you sometimes it just hangs on suspend and I have to hard reset the laptop... I ended up using the version 5.13.0-27 and no more problems ! In Grub, select Advanced options and pick kernel 5.13.0-27
