Computer will reboot itself, new behaviour | Linux Mint Community🍵 | Page 1

#

I have been on Linux for 5 days now. It was fine until yesterday evening.

Behaviour:

Computer is on
Menu>shutdown
Computer turns off
After 2-3 seconds, it will power back on
It will boot to a blank terminal instead of grub
This terminal can be typed in freely, no commands return anything. Not even gibbierish will return an error.
After some time, it will return "Timed out for waiting the udev queue being empty."
It will then boot to mint.

Only changes I am aware of was stuff related to inputremapper and Solaar.

Other things:

Today, linux warned me it was running out of space. var/log was using over 100GB and filled with the attached screenshot.

https://www.youtube.com/watch?v=I8u5CabMz1I << by BTNHD, 5 minute video on how to make a SWAP FILE

#

do a fresh reboot, then make the swap

#

if still has issues, roll back to 6.14 kernel

fresh sable May 6, 2026, 9:04 AM

#

Part of me is concerned I am unable to do a fresh boot. From what reasearch I have done, suggests that the PC is not actually fully shutting down.

#

The fans turn off and the lights turn off, but apparently things can still be awake inside

#

The OS was installed 4 days ago-ish

The boot param was my attempt at supressing the logspam. It did not work.

supple robin May 6, 2026, 9:09 AM

#

yes

#

turn the top switch on, and put timeout to 5

#

then save

#

then close sys admin app, and press ctrl-alt-backspace

#

from login mgr, choose the shutdown icon

#

see #1297240853206532136 message if need to roll back and use 6.14

supple robin <https://www.youtube.com/watch?v=I8u5CabMz1I> << by BTNHD, 5 minute video on ho...

The following will create a 2 gig swapfile (1 MiB x 2048)
Adjust to suit your size accordingly.

sudo dd if=/dev/zero of=/swapfile bs=1024k count=2048 (make big empty file)
sudo chmod 600 /swapfile (set linux read/write permissions on file)
sudo e4defrag /swapfile (defragment the file)
sudo mkswap /swapfile (transform the big file into usable swap)
sudo swapon /swapfile (turn on swap (virtual memory) on in the system)
free -h (test to view that swap memory is now in play)

sudo xed /etc/fstab (edit the fstab file to make swap automatically available on each boot)

(put this into the fstab file on new line near bottom) :
/swapfile none swap sw 0 0

(save the fstab file and exit the editor)

sudo reboot
free -h (once booted back to desktop, to check memory and virtual memory (swap) )

#

summary ^

#

u can use count=1024 for 1 GiB swapfile

fresh sable May 6, 2026, 9:21 AM

#

Ok. So good news and bad news.

Boot correctly booted to grub, like it did before.

Bad news

It still booted by itself, it still waited for ages on the blank terminal

#

'scuse the grubby screen. I hope that this helps.... I recorded the process and am uploading it now

#

supple robin May 6, 2026, 9:26 AM

reboot, from grub> mint advanced

#

choose old kernel and boot

fresh sable May 6, 2026, 9:29 AM

#

Ok, that booted perfectly. No hanging. But I did a quick test and it still rebooted by itself.

#

Weird that this only started yesterday

i say make it now. at least 1 GB

fresh sable May 6, 2026, 9:35 AM

Ok

supple robin May 6, 2026, 9:35 AM

supple robin u can use *count=1024* for 1 GiB swapfile

.

#

follow the summary

#

dont do anything else while it's working

#

to defrag n all

#

when rebooting, still choose the 6.14 kernel from Advanced

fresh sable May 6, 2026, 9:39 AM

#

It only took a moment to defreg.

It is rebooting now.

All of the drives are recently formatted. When I moved from windows, I sorted all data and reformatted the drives to ext4 before moving stuff back. I wanted to abandon windows entirely

supple robin May 6, 2026, 9:40 AM

Installing now

supple robin May 6, 2026, 9:45 AM

#

incase 6.14 proves unstable, boot from 6,8 and run it a day or 1000, if it's stable

#

6,8xx is the long-term-support one anyway

#

also decline any further linux image 6.17 offerings in the updates list

fresh sable May 6, 2026, 9:47 AM

#

Ok. 6.8 installed.

supple robin May 6, 2026, 9:47 AM

#

hopefully u dont gdet more logs

#

u can use disk usage analyzer to monitor things for space, and what is taking it

#

would also reco. a timeshift save

fresh sable May 6, 2026, 9:48 AM

#

Will this resolve the auto booting?

I did do timeshift, I set one up on my first day on the OS

#

It is set weekly

#

I assume I should go boot to the new kernel now too?

supple robin May 6, 2026, 9:49 AM

#

is it saving to the other drives or to the EVO?

#

Not that it matters that much, but, u do have 5 drives

fresh sable May 6, 2026, 9:50 AM

#

I am not sure. My boot partition was intended to keep as clean as possible. I have been installing flatpacks to my 6TB drive

#

/home is redirected to said drive

supple robin May 6, 2026, 9:50 AM

#

*4 drives

#

u can easily review timeshift settings.

#

hit the settings button on its toolbar

#

it will show snapshot save location

fresh sable May 6, 2026, 9:52 AM

Yeah, it is storing to the 970. But it will only keep 3 so not too fussed

It will boot to a blank terminal instead of grub

#

is this solved?
