Kubuntu 21.10 freezes after 3-4 hours and can't reboot succesfully

I just installed my Kubuntu recently it and it freezes after about 3-4 hour of usage. Keyboard event still works but I can't click anything. The only way I could do is pressing power button to shutdown and power it again, but it is still freeze after rebooting. The only way I could do to make it work again is opening Live CD, run sudo fsck -f my linux root partition, which is /dev/sda3 in this case, reboot and my Kubuntu will successfully work again. But then the problem will happen again if I use it for several hours. Any help is appreciated or please tell me what command to show you the log you need to help diagnostic

My laptop's spec:

  • AMD Ryzen 5 4600H
  • NVIDIA GeForce GTX 1650 4GB
  • 256GB nvme SSD and a 500GB SATA SSD that replaced my laptop's DVD drive, which I installed my Kubuntu on /dev/sda3 (root) and /dev/sda4 (/home)

Output of neofetch

The sudo fsck -f /dev/sda3 log that last freeze I run https://pastebin.com/MyjNxQyc

The backup GPT table is corrupt, but the primary appears OK, so that will be used.

Hey, Can you tell me what apps were you using when it freezes, also as you said the keyboard works but the mouse doesn't work, I believe you are on a laptop with a touchpad, as this is a common problem, also can you post the output of `free -h` command

@someone I mainly use Vivaldi browser and Visual Code on my Kubuntu, so I think those are apps when it freezes. I added the log at the end of my thread. Thanks for helping

Ok yeah, it is not a memory issue but can you also post the output of `neofetch` generally, it lets people know about your system specs and other things, which is useful

Have you done a custom kernel upgrade ?

Yes. Initially, the kernel is 5.13.0-22 and the issue already happened at that time. I updated my kernel to 5.15.6 using https://github.com/pimlie/ubuntu-mainline-kernel.sh but it doesn't fix the issue

Normally you should not do that ! That could cause more errors

At that time, some search results I found said kernel 5.13 doesn't have good supports with Ryzen CPU and newer versions will fix some bugs so I updated it in hope that it could fix my issue

That is true, that kernel 5.13 doesn't have support for Ryzen a lot, I also use Ryzen 9 and have the same issue but upgrading to the newest kernel version whithout testing it isn't good

You're getting I/O errors on /dev/sda3 which **might** suggest a bad SSD. What is "Candy Bay"? Is /dev/sda3 an external USB drive? Is it a USB3 or USB2 drive... plugged into a USB3 or USB2 port? Do you dual-boot with Windows? Edit your question and show me `grep -i FPDMA /var/log/syslog*` and `grep -i sda3 /var/log/syslog*`.

@heynnema /dev/sda is a SSD drive that replace my laptop's DVD drive. I added the result of your suggested commands at the end of my thread

So the SSD is a SATA drive? You dual-boot with Windows. Have you installed a Windows driver that purports to allow read/writes to Linux ext2/3/4 partitions? Use the `Disks` app and show me the SMART Data for the drive in question.

@heynnema is KDE partition mangager ok too? I added a screenshot of the drive's SMART log at the end of my thread

Hum, the SMART data didn't reveal anything. Let's try a mod of a previous command... do `grep -i sda /var/log/syslog*`. Also, you didn't answer my question about the Windows driver. Is there any chance that the drive isn't seated properly into the DVD SATA connector?

I'm very sorry for very late response. Thanks for your presistence I tried to use it a free days to see if the issue stills happen. Unfornately, it still happends 1/ I updated KIOXIA's new firmware 2/ I couldn't find Samsung Magic for my SSD. Look like they don't support for this PM991 SSD 3/ the swap is rarely used. the `used` number is often stay at 0

4/ The "The backup GPT table is corrupt," error hasn't appeared again so far. I also can't find how to rebuild GPT table without wiping data 5/ Yes I dual-boot but I don't install any Windows driver to read Linux partitions. 6/ I recently install Kubuntu and its /home partition on my Samsung SSD and haven't seen the crash so far.

Freezing

Use the free -h command to monitor swap used. If it approaches 3G, you'll need to add a /swapfile, or increase the /dev/sda5 swap partition.

KIOXIA EXCERIA 480

Update the firmware to the March 15, 2021 version. Also get the SSD Utility Management Software. Get them here.

SAMSUNG MZALQ256HAJD-000L2

Error: The backup GPT table is corrupt, but the primary appears OK, so that will be used.

Rebuild the GPT table. KDE Partition Manager may be able to do it. Check the firmware. Get the Samsung Magician software here.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
