So I have been using Ubuntu 22.04 LTS on my laptop for more than a year now, but recently I have experienced unexpected freezes or hangs. And when that happens, nothing works, not even virtual terminal. The only thing I can do is restart by the power button. I have used journalctl -b -1 -e to get error logs and this is the result:

Some assistance will be greatly appreciated about what I should do now.

Also here are my PC specs should that provide any info:

  • System "freezes" are often caused by running too many, too large programs and running out of available memory. Use free to see if you have swap space, read man mkswap swapon fstab fallocate to create some. Swap space must be contiguous. use mkswap or fallocate, not dd. Traditionally, swap space of 1.5 × RAM has been recommended, but YMMV. If you don't plan to hibernate your system, you can have less than 1.0 × RAM. – waltinator Dec 12 '23 at 16:08
  • So this is my swap size 11144588 but used 0, so they are all free. And I checked the swappiness to be 60. – Imran Farid Dec 12 '23 at 16:16
  • Have you tried a memtest86 to check if your memory has developed a fault? Seems a bit strange that it's only started recently. In addition to the already mentioned commands, the htop command can be used for realtime monitoring of resource use – moo Dec 12 '23 at 23:37
