I got chrony instead of ntpd and it has a line "makestep 1 -1" in it's config allowing infinite number of big time corrections. For some reason it did not helped.

There are relevant topis on the forum for A64:

The only difference is that A64 jumps forward.

I found no related issues on github or forum for H3 specifically.

Does any one else experience this issue?

The original clock jump issue is really a jump in the future, not in the past ...

Do you have any network/internet issue that prevent having NTP working properly ?

Yes, I know that the original issue is about jumping in the future.

No, I do not have any network issues.

 

Both ntpd and chrony maintain correct time until it jumps back to 1978. After that

rcu: INFO: rcu_sched self-detected stall on CPU

OOM killer unhinges and starts killing processes left and right

I also saw many cron processes and eMMC was thrashing.

I just want t get to the bottom of these random time jumps. Sometimes it takes several days, sometimes it takes a month of uptime for it to happen.

This looks similar to the issue in this post:

CPU stall followed by clock getting set to an incorrect time. I think the clock issue is a symptom rather than a cause. I didn't see anything obvious in the call stack of this issue or the referenced issue but I'm not very good at reading those. Maybe someone who knows more can compare these posts and see if a root cause is obvious.

Hi, 

 

I have encountered this issue for many times on OrangePi PC,  this issue happened by using following version 

  • Armbian version: 5.41, Kernel version: 4.14.32
  • Armbian version: 5.77,  Kernel version: 4.19.25
  • Armbian version: 5.90,  Kernel version: 4.19.57

I have more than 10 Orangepi PC running busy tasks at the same time, and this issue happened more than 15 times in the past year, still have no idea how to deal with this,  it is still able to send data to my server somehow, which means that the internet connection is available, but i'm not able to ssh.

 

I have tried the following methods:

  • Wrote a udev file to copy all system log when usb pendrive is detected,  this works fine when device runs normally, but not working when encounter this issue.
  • Using watchdog, works fine if using fork bomb to test, but not able to recover from this issue
  • Tried connect to a keyboard and hdmi monitor,  this works fine when device runs normally, but not working when encounter this issue.
  • Using TTL serial to usb adapter,  I'm able to control device when it runs normally, but not working when encounter this issue. 

 

I found that dmesg record some error message as below when I encountered this again yesterday

Currently, I might try to continuously detect whether this error message occurred in dmesg, if yes, I will try using this command "sudo systemctl --force --force reboot"(it seems that /sbin/reboot does not work at the moment)
