Laptop freezes frequently

Hi My laptop hangs frequently, and couldn't able to figure out wether it happens due to firefox or something else.

Is there any method to see what exactly causing my system to hang??

Please find the dmesg log over here.

dmesg log

my lspci log:

Re: Laptop freezes frequently


You can try to start gather informations like so, this probably won't tell you exactly what's the issue, but it can help you pinpointing it

  • Look at logs around the time it freeze, is there something recurrent in there ?

  • Is it something recent ? Like if you never had freezes before it might be worth trying an LTS kernel for example.

  • Hardware-wise, try a memtest for good measure and also check temperatures, laptops are known to overheat easily.

  • What "type" of freeze is it ? is it only X or the whole thing ? Is it only for a few seconds and then it continues like nothing happened or do you have to restart it completely ?

  • The good old trial and error technique: "maybe it's related to my graphic driver but i don't have any logs, let's try using mesa for a few days and see if it freezes"

In your dmesg we can lines about an mce hardware error, that might be worth investigating (there's tools for those) but i don't know enough to be able to tell you if that can be related to your freezes.

Carefully explaining your problem is half the solution.

Re: Laptop freezes frequently

In my case it is most probably due to iwlwifi driver, as it only happens when I'm using WiFi. I haven't had this issue while I was using Ethernet connection.
