  • You should [edit] your question and enter any requested information right into your original text and not give links to some obscure web sites! – FedKad Feb 10 '22 at 07:16

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

  • No wrong 1 is i have good amount of ram unused like more than 5-6gb of it free. And swap 3gb created which is unused so no lack of ram and i have a very good fast nvme m.2 ssd and it is actually pretty fast so no hdd here. – limanux Feb 12 '22 at 07:14
  • Can i get some feedback to solve my issue else i ahve to reflash – limanux Feb 13 '22 at 16:26

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
