Ubuntu Crash after watching long youtube videos

us flag

I have experienced a confusing problem using a quite newly installed Ubuntu 20.04.2.0 LTS.

When using Ubuntu normally everything works fine. As soon as I have a long youtube video (<30 mins) in Firefox playing - somewhen during the playtime of the video the Ubuntu UI will freeze, the audio will play a few seconds longer, before all goes black and I am left alone with my mouse cursor for a few seconds before this error message is displayed:

[10752.211584] EXT4-fs error (device sda2): __ext4_find_entry_1535: inode #31983115 comm gdm-session-wor: reading directory Iblock 0

[10752.211654] Buffer I/O error on dev sda2, logical block, lost sync page write

[10752.211688] EXT4-fs error (device sda2): I/O error while writing superblock

Interestingly this error appeared on 2 different SSDs (one old, one new) using a bootable USB stick with Ubuntu 20.04 LTS from the official page for installation - no custom installation, just the standard installation procedure.

As I have found no solution to a similar issue here or elsewhere on the internet, I´m looking here for help!

Hello. Can you describe your computer? How much ram do you have? can you post the output of "free -h"?. My experience on this is RAM and swap memory tunning.

Your trace clearly shows, that your hardware (sda2 in this case) has errors. Try `fsck` (sda2 must be unmounted) to fix it. If no broken inodes are found, the problem lies deeper

@kanehekili I assume I have to apply this command from the live usb system, as sda2 is my main partition for ubuntu - or did i do something wrong?

Well. It is not ram nor swap. that points to the disk activity as you trace says, but the estrange thing is that you say happen on two different ssd drives. Have you tried the same on another browser?

@jpbrain yes one drive is actually a brand new Samsung 860 SSD, which I sector tested before installing Ubuntu on it. I will test this on Chrome too - maybe then it'll stop happening...

are the drives ssd or nvme? to do the check "fsck", you can use a bootable pendrive. Also you can install nvme-cli (for nvme) and gsmartcontrol (ssd) to know more about the drives.

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.
