Regular complete lockups

cn flag
Nicholas Mazower

I'm a new user of Ubuntu and Linux. I installed it for the first time about 3 months ago.

Starting about 2 months ago i've been having more and more frequent freezes that completely lockup my machine. Mouse doesn't move and audio loops. I then have to forcefully shutdown the machine. A month ago the crash bricked my SSD and so I am on a fresh install of Ubuntu 20.04.2 LTS.

I'm new to this sort of troubleshooting so the issue could be very simple.

Any help is very appreciated

Edit your question and show me `free -h` and `sysctl vm.swappiness` and `sudo lshw -C memory` and `ls -al /var/crash` and `swapon -s`. Start comments to me with @heynnema or I'll miss them.

After a "sudden shutdown", aka "system crash", and reboot, the terminal command `sudo journalctl -b -1 -e` will show you the end of the previous boot's log's. If there is no hint there, suspect power/ overheating. Read `man journalctl` to see how to extract information from the logs. You can find how I make use of `journalctl` easier at `https://askubuntu.com/users/25618/waltinator`.

@waltinator I ran that and and added its output to my question. However i'm not sure if the LED controller is an issue. This is from the crash I just had. To clarify, the machine doesn't turn itself off. It locks up and then I have to force shut it down.

Thanks for the data that I requested. Helpful. Is this a laptop or a desktop computer? What processor? Do you know how many DIMM/SODIMM memory slots that you have? Tell me the EXACT make/model of your motherboard. Does the machine operate ok for a while, and then sometime later, have this problem? Edit your question once more and show me `ls -al ~/.local/share/gnome-shell/extensions` and `ls -al /usr/share/gnome-shell/extensions`.

@heynnema This is a desktop. It has a Ryzen 5 3600 as CPU. The motherboard has 4 slots. It is a ASRock B550 Taichi. The machine runs fine for a while and then has the issue. It appears to loosely correspond to load, lately playing a new computer game it has been doing it every 30 minutes to hour. I shall do the commands from your answer now

Is CPU or RAM overclocked?

I can't get to the User Manual at the ASRock web site. I want to check that you have the RAM installed into the correct slots. Maybe you can check later for the UM.

@heynnema I have adjusted the swapfile and run the memtest and it passed. My RAM is running an XMP profile but only to bring it to the specifications of the RAM, G Skill Intl / F4-3200C. I may be misinterpreting the journalctl results but the last thing I see there is the LED controller so I have disabled the motherboard LEDs. A different source also mentioned AMD's SVM causing an issue so I have disabled that. I will see if I get a crash within the next couple of days.

@NicholasMazower Good! When I said retest, I didn't mean to re-run memtest. Sorry. So now run without XMP and see if things improve with the lockups/freezes.

@heynnema it was off. This may be a bit hasty but after some more googling showed other people on 20.04 experiencing the same issues I've jumped to 21.04. Will see if the issue persists tomorrow

@heynnema I've unfortunately had two more crashes. First one even the mouse didn't move. Second one the mouse did move. I'm rather befuddled at what it could be. Maybe a hardware issue but not the RAM?

In looking through the logs I found some references to 'nvidia_frontend_unlocked' right before the crash. So i'm changing the display drivers again although I had done it before and that didn't stop the crash. But perhaps i have more than one kind of crash happening.

@NicholasMazower You can boot to the GRUB menu, edit in `nomodeset`, that would eliminate a video driver problem. Do you know how to do this, or do you need more instructions? Did you update the Nvidia driver after updating to 21.04?

@heynnema Instructions would be very greatly appreciated.

@NicholasMazower Boot to GRUB menu. Highlight the desired boot selection. Hit the "e" key to enter edit mode. Use arrow keys to find "quiet splash" and change it to "quiet splash nomodeset". Hit control-x or F10 to continue booting. This is a temporary change, and will go away next reboot. Screen resolution may be off, or difficult to set. But the idea is to see if there are any crashes/freezes. Did you update your Nvidia driver?

@heynnema Thank you very much! I was on the 465 nvidia driver and i've gone down to 460 in hopes of stability. I didn't realise Nvidia had such terrible Linux support when I built the machine. I'll wait until the next crash in case the driver change worked.

@heynnema No crashes since last communication. I'm tentatively marking this as solved. A combination of driver updates, ubuntu updates and swap file increases.

Disabling "Automatic C-State Management" or "Global C-State Control" or similarly named option in BIOS is what helped me with a similar problem.

/swapfile

Your 2G /swapfile is too small. Let's 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 32G 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

Memory

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.

Update #1:

Disable XMP, reboot, and retest for lockups/freezes.

Update #2:

Updated from Ubuntu 20.04.2 to 21.04 and so far no crashes!

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.
