Problem with shutting down/rebooting

[Mirdarthos]

Hi @qqtrol, and welcome!

Tip:

In the future when posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:

```
pasted text
```

This will just cause it to be rendered like this:

Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.

Instead of like this:

Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby increasing legibility thus making it easier for those trying to provide assistance.

On this forum here you need to have Trust Level 1 (=TL1) to be able to post screenshots and links in-line.

That’s dumb! Why is that?

Well, that’s because on our old forum we got tons of screenshots of text, links to SPAM, PR0N and other things you don’t want on a forum, so all the new users are prohibited from posting links and pics because of a few bad actors.

I’m no expert, but this should give you a clue:

@qqtrol

“echo 0 > /proc/sys/kernel/hung_task_timeout_secs” disables this message.

So try exactly that. From a terminal, run:

echo 0 > /proc/sys/kernel/hung_task_timeout_secs

And see if it helps. Hope it does!

Edit:

According to this page, doing that is a bad idea:

This is because a “hung_task” is generally not a good message and this task being blocked for as long as 120 seconds affects the server and the Linux kernel performance.

The page also provides further troubleshooting instructions:

To further inspect the kernel ring buffer, run these commands:

dmesg | grep hung_task
dmesg | grep kernel

Inspect the output for INFO, ERROR or WARNING and if you find several repeated entries that mentions a “hung_task” or show a hardware device issue

So, let’s inspect it. Please provide the output for:

sudo dmesg | grep --ignore-case 'kernel|kworker'
