This message has comeback when rebooting. I got rid of this message or at least hide it way back when. For some reason it’s back. I just don’t want to see this message when rebooting. How do I do that?

check with these commands:
cat /proc/sys/kernel/watchdog
cat /proc/sys/kernel/nmi_watchdog
both should return ‘0’ if watchdog is disabled

According to arch wiki - some has reported the need to use a blacklist

@wildcard . There is an older post on this topic as well about what @linux-aarhus has quoted

https://forum.manjaro.org/t/watchdog-did-not-stop/83414

Hope this helps

Thanks! But I’ve already done all of this years ago. For some reason they don’t work anymore.

From:

Make backup a default grub file:

sudo cp /etc/default/grub /etc/default/grub.bak

Edit grub file in Your favorite text editor. For this HowTo I used nano.

sudo nano /etc/default/grub

Find line:

GRUB_CMDLINE_LINUX=""

Disabling Watchdog feature

nowatchdog

…don’t forget to

sudo update-grub

NOTE: blacklist Watchdogs modules too:
/etc/modprobe.d/blacklist.conf

blacklist iTCO_wdt
blacklist iTCO_vendor_support

Thanks, but I already have all of this before the issue came back.

Did you check this:

Improving performance - ArchWiki

the boot parameter (depending on the correct name for it) should work

as well as the additions to the grub command line.


If it does not work
show your work :wink:

Hi,
Although I could not find the message which appears when I restart the system I also did the changes suggested in the posts and the result is the following:

cat /proc/sys/kernel/watchdog
0
[jochoa@nbjochoa ~]$ cat /proc/sys/kernel/nmi_watchdog
0

[jochoa@nbjochoa ~]$ cat /etc/modprobe.d/blacklist.conf
blacklist iTCO_wdt
blacklist iTCO_vendor_support

[jochoa@nbjochoa ~]$ cat /etc/default/grub | grep nowatchdog
GRUB_CMDLINE_LINUX="nowatchdog"

[jochoa@nbjochoa ~]$ journalctl -xe -b | grep watchdog

Maybe, I missed some configuration.

Regards,

i had a similar issue. after issuing nowatchdog and blacklisting the two modules, i would still get watchdog did not end errors during reboots still. i had to also add nmi_watchdog=0 after nowatchdog.

so my grub line looks like the following:

GRUB_CMDLINE_LINUX_DEFAULT=“quiet resume=UUID=c11af399-b978-4bf0-9ef0-16d97c8cb8af udev.log_priority=3 nowatchdog nmi_watchdog=0”

edit:
scratch the above. on another reboot, i received another watchdog didn’t shutdown error again. so digging into it more, wdctl was showing me:

sp5100

was in use. so i added blacklist sp5100_tco to my blacklist.conf file and now watchdog is finally disabled for good. i also removed nmi_watchdog=0 from my grub line and just kept nowatchdog instead. wdctl is now reporting:

wdctl: No default device is available.: No such file or directory

so for j8a, your wdctl is reporting

wdat_wdt

so i would find the exact module name for that and blacklist. that should fix your problem. you still have one more watchdog module running. that’s your issue.
