Shutdown takes much longer

Support
1

Recently Manjaro takes much longer to shut down(feels like minutes sometimes, but i did not time it), and just before it does, for a second there is red and white text on the screen.

Are you certain that you have locale settings defined in Manjaro settings Manager-Locale settings? An update some time back erased my settings and I had to set them manually.

3

Under Local everything has a value, i think that is a left over from solving a bug with kde sometime ago. Do you think that is actually the reason?

4

Do you have a CD/DVD in the drive? If so, eject it and try to power off again.

5

I don’t have one in the drive.

6

sr0 is usually an optical drive, that’s why I asked. Your journal only shows errors concerning sr0.

Try jurnalctl -b-1 (without -p3).

7

I have windows on a second harddrive, could that be the reason?

EDIT: That is 11245 lines is there an easy way to copy all this, i don’t seem to be able to copy it all in one go?

8

Try journalctl -xe -b-1. If it is too long use pastebin.

So … uh … whats that ‘oldroot’ directory thats mounted and seems to not want to unmount?
(its not standard … so its something particular to you)

I think thats something from the live image…

Try to disable watchdog. Upon boot press e at the grub menu entry, then go to the end of the linux line and write nmi_watchdog=0. Here’s how mine looks for an example (ignore the other parameters I have there):

linux   /vmlinuz-5.4-x86_64 root=/dev/mapper/vgManjaro-lvol0 rw  resume=/dev/vgSwap/lvol0 quiet scsi_mod.use_blk_mq=1 zswap.enabled=1 zswap.max_pool_percent=13 zswap.compressor=lz4 zswap.zpool=z3fold nmi_watchdog=0 mitigations=off

The press F10 (I think) to continue booting and then test it.

It would be good to clarify this. Do you mount it manually or what?

13

I don’t have it on my current system, but i remember having seen it when using the live medium.

14

I have no idea waht oldroot is, but i found this in the archived manjaro forum:

Is that the line where i should add nmi_watchdog=0 it looks quiet a bit different compared to yours.

When i “installed”/connected my windows drive it, i booted it in manjaro and ran sudo update-grub after that at launch i get a screen where i can choose. I don’t think that counts as manually.

15

Yes, navigate to the line starting with linux, click END, SPACE and type nmi_watchdog=0 then press F10.

It’s system specific and I have some personal settings there. That’s why it is so different.

16

I’m not sure I understand this. You can choose what and where? And, is Windows on an external drive also? Or have you removed it with fear of overwriting it when installing Majnaro?

17

I can select the os i want to boot here. Yes Windows is on a seperate hard drive, but it is internal not external. I Removed it in case i broke something and installed Manjaro on a fresh SSD. After the installation i connected it again.

Adding nmi_watchdog=0 solved the issue and i no longer get the error message. My Shutdown time is also back to normal.

EDIT: Thank you for the help

Ok, to make it permanent edit /etc/default/grub and add it to end of the line starting with GRUB_CMDLINE_LINUX_DEFAULT=, like this (ignore the rest of my personal parameters):

[mbb@mocho-desktop ~]$ cat /etc/default/grub
[...]
GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/vgSwap/lvol0 quiet scsi_mod.use_blk_mq=1 zswap.enabled=1 zswap.max_pool_percent=13 zswap.compressor=lz4 zswap.zpool=z3fold nmi_watchdog=0 mitigations=off"
[...]

You can see these are the parameters appearing in the linux line edited above.

Save your changes and then issue sudo update-grub to make it permanent.

19

Out of curiosity, do you know what actually caused it? Did i break something?

20

No, everything is fine. Watchdog is a kernel component which makes sure the system is responsive. Sometimes it just doesn’t stop on shutdown/reboot, or can’t stop a certain process from executing. I always disable watchdog on my systems. This is more useful for remote systems needing constant uptime.
