Computer fails to reboot "watchdog did not stop" "waiting for process systemd-udevd"

System Information

  • DietPi version
    G_LIVE_PATCH_STATUS[0]=‘not applicable’
  • Distro version: bullseye
  • Kernel version: Linux DietPi 5.10.0-21-amd64 #1 SMP Debian 5.10.162-1 (2023-01-21) x86_64 GNU/Linux
  • Architecture: amd64
  • SBC model: Native PC (x86_64)

System reboots on a cronjob at 6am every day and sometimes it just fails to reboot. It happens randomly maybe 1-2 times per month and I can’t SSH to the system when it happens so I had to connect a monitor and wait for the problem to happen again. Took a picture of the last output, which showed the same thing both times it happened so far:

Anyone’s got any idea what this does specifically? Checked Google but the information I found wasn’t really helping with my level of knowledge. Is it possible it’s a kernel bug as per this post? Later kernel version though.

NOTE: No USB flashdrive connected (only a USB keyboard) and there is no dedicated GPU (There was one before but I removed it a while ago)

Please enable udev debug logging to hopefully get more output when this happens:

G_CONFIG_INJECT 'udev_log=debug' 'udev_log=' /etc/udev/udev.conf

This adds quite a large number of system logs (especially at boot), so might be worth it to try triggering the issue directly with some reboots or so.

Thanks friend,

Just came here to say I still don’t have any info yet since the freeze doesn’t happen often, but I’ll report back as soon as I get it :slight_smile:

If it somehow doesn’t freeze anymore, even better. Otherwise jep, just report back with hopefully additional logs when it happens again.
