Help with understanding log

Question

just installed Ubuntu 20.04. the system keeps freezing and i have to turn it off with the power button and on again. Can someone help me analyze this log file, if there's maybe something wrong that i'm unaware of?

Have you [tested the storage device](https://askubuntu.com/a/1226389/1222991) to see if there are issues? — matigo, Jun 05 '21 at 15:09
when i enter the command i get: ar@Aruntu:~$ sudo badblocks -sv /dev/sdb badblocks: No such file or directory while trying to determine device size — Arsenio Rechards, Jun 05 '21 at 15:37
Do NOT use `badblocks` directly. Very bad. Use `e2fsck -fccky`, or a variation thereof. — heynnema, Jun 05 '21 at 16:26
Edit your question and show me `free -h` and `swapon -s` and `cat /etc/fstab`. Start comments to me with @heynnema or I'll miss them. — heynnema, Jun 05 '21 at 16:27
@matigo Do NOT recommend using `badblocks`. See `man badblocks` and you'll find "For this reason, it is strongly recommended that users not run badblocks directly, but rather use the -c option of the e2fsck and mke2fs programs." — heynnema, Jun 05 '21 at 16:29
@heynnema thanks, please see the question for information you requested. — Arsenio Rechards, Jun 05 '21 at 16:40
@heynnema , i added the information in my question please check. i have not enabled zswap. — Arsenio Rechards, Jun 06 '21 at 17:28
@ArsenioRechards Everything looks good there now. Do you have a Ryzen processor? If so, go to https://www.memtest86.com/ and download/run their free `memtest` to test your memory. Get at least one complete pass of all the 4/4 tests to confirm good memory. This may take many hours to complete. — heynnema, Jun 06 '21 at 18:04
@heynnema ,i just downloaded, i'm gonna try it i have a Lenovo V14 with a AMD Athlon Gold 3150U with Radeon graphics. 12GB DDR4, 512GB Nvme ssd — Arsenio Rechards, Jun 07 '21 at 15:26
@heynnema, all 4 passed!i think i'm gonna try reinstalling 20.04. format and start from scratch, thanks for your support. — Arsenio Rechards, Jun 08 '21 at 15:33
@heynnema, yes I will. Thank you once more for your support, i appreciate it. — Arsenio Rechards, Jun 08 '21 at 16:28
@heynnema, i just did the reinstall but it already froze once.not during install. i think maybe this laptop model has some issues, it's a brand new machine. it really happens randomly.I'm a bit sad because i really want to switch to Ubuntu. — Arsenio Rechards, Jun 12 '21 at 00:40
Did you ever do the `memtest` that I requested? Also show me `sudo lshw -C memory` and `sudo dmidecode -s bios-version`. — heynnema, Jun 12 '21 at 01:44
And also tell me the EXACT model # of the laptop... V14-xxx. — heynnema, Jun 12 '21 at 01:50
@heynnema Lenovo V14-ADA, i added 8G memory and 512nvme. i did do the memtest and passed all of them,there was a html report but i don't where it was saved.please see info in question — Arsenio Rechards, Jun 12 '21 at 02:10
Good on `memtest`. Thanks. Show me `free -h` and `sudo lshw -C memory` and `sudo dmidecode -s bios-version`. — heynnema, Jun 12 '21 at 02:13
@heynnema, Noted. I increased the swapfile successfully,however to update the bios i need the windows platform, i tried updating from a windows vm but that doesn't work. so this means i'll have to install windows on this laptop in order to update the BIOS. — Arsenio Rechards, Jun 12 '21 at 11:12
@heynnema, I just updated BIOS. let's monitor and see what it does — Arsenio Rechards, Jun 12 '21 at 12:31
@heynnema,No success it just kept freezing more and more. i switched to Fedora 34, and guess what!the same thing happens. i'm unable to work so i think i'm gonna switch back to windows for now, i will try linux when i have different hardware,thanks for your support! — Arsenio Rechards, Jun 12 '21 at 19:24

Your /etc/fstab is incorrect.

It shows three entries for /swapfile...

/swapfile                                 none            swap    sw              0       0
/swapfile none swap sw 0 0
/swapfile none swap sw 0 0

Edit your /etc/fstab using the terminal application, with the command sudo -H gedit /etc/fstab, and remove the first two /swapfile lines, and leave the third /swapfile line, save the edited file, and then reboot.

Extra note: Don't use badblocks or e2fsck to bad block a SSD/nvme.

Update #1:

BIOS

Lenovo V14-ADA

You have version E8CN25WW, dated 10/13/2020. There's a newer BIOS available, version E8CN27WW, dated 05 Feb 2021, and can be downloaded here.

Note: Confirm that I have the correct web page for your model #.

Note: Have good backups before updating the BIOS.

SWAP

Your 2G /swapfile is too small. We'll increase it to 4G...

Note: Incorrect use of the rm and dd commands can cause data loss. Suggest copy/paste.

In the terminal...

sudo swapoff -a           # turn off swap
sudo rm -i /swapfile      # remove old /swapfile

sudo dd if=/dev/zero of=/swapfile bs=1M count=4096

sudo chmod 600 /swapfile  # set proper file protections
sudo mkswap /swapfile     # init /swapfile
sudo swapon /swapfile     # turn on swap
free -h                   # confirm 12G RAM and 4G swap

Edit /etc/fstab, using sudo -H gedit /etc/fstab or sudo pico /etc/fstab.

Confirm this /swapfile line in /etc/fstab... and confirm no other “swap” lines... use SPACES in this line... confirm NO TABS...

/swapfile  none  swap  sw  0  0

reboot                    # reboot and verify operation

Update #2:

This computer freezes with Ubuntu and Fedora 34. Switching back to Windows for now.

Hi, i'm new to this so can you please be more specific? what do you mean by "remove the first two lines"? how do i remove the lines? – Arsenio Rechards Jun 05 '21 at 16:56
@ArsenioRechards I updated my answer for you. – heynnema Jun 05 '21 at 17:02
@heynema, thank you for your support. i did the commands i will monitor the system for a day or two, if it doesn't happen again i will sure mark this answer as correct. – Arsenio Rechards Jun 05 '21 at 18:07
@heynema, Hi it just happened again while i was running a VM it also happens randomly even with no VM running. do you see any other thing in the log that might cause this? – Arsenio Rechards Jun 05 '21 at 19:49
Show me the `cat /etc/fstab` again, and upload /var/log/syslog to paste.ubuntu.com and give me the URL and I'll take a look for you. Ping me when it's done. – heynnema Jun 05 '21 at 20:15
i added the cat /etc/fstab to my question please check, for some reason i'm not able to post the log,i get an error bad gateway after i click paste can i share it with you another way? – Arsenio Rechards Jun 06 '21 at 00:39
@ArsenioRechards Your /etc/fstab is still showing 3 /swapfile lines. I thought that you had edited that. At paste.ubuntu.com you tried to paste your clipboard that contained the output of `cat /var/log/syslog`, yes? – heynnema Jun 06 '21 at 00:46
,see url for pasted data https://paste.ubuntu.com/p/m7q8dyNJVX/ i removed the lines correctly – Arsenio Rechards Jun 06 '21 at 11:24
i also added another log please check, i only added the part where the machine froze, between 8.48 & 9:13, do see something that might cause the freeze? – Arsenio Rechards Jun 06 '21 at 12:27
https://paste.ubuntu.com/p/XgtZbZT4zk/ – Arsenio Rechards Jun 06 '21 at 12:38
@ArsenioRechards I'm still seeing "Jun 6 08:12:08 Aruntu kernel: [ 2.672474] systemd-fstab-generator[236]: Failed to create unit file /run/systemd/generator/swapfile.swap, as it already exists. Duplicate entry in /etc/fstab?" in syslog. Based on the last `cat /etc/fstab` that you showed me, it doesn't look like you removed the extra /swapfile lines. Am I missing something? – heynnema Jun 06 '21 at 15:03
@ArsenioRechards Have you installed/enabled zswap? – heynnema Jun 06 '21 at 15:04
@ArsenioRechards What video card? What version driver? Show me `sudo lshw -C video`. – heynnema Jun 06 '21 at 15:04
@ArsenioRechards Edit your question and show me `ls -al ~/.local/share/gnome-shell/extensions` and `ls -al /usr/share/gnome-shell/extensions`. – heynnema Jun 06 '21 at 15:07
