pine64: massive date/time clock problem

Recommended Posts

Hello,
I have a massive problem as the time/date on my Pine64 keep changing randomly to the year 2113.

In my project, I use several Pine64s and the problem now occurs on many of these Pine64s. Unfortunately I need the correct time for my project.

I am using the following system: ARMBIAN 5.32.170911 nightly Ubuntu 16.04.3 LTS 4.13.0-sun50iw1 (with additional overlays = uart3 and
console = ttyS3)

Could this be due to the error described in the post

and is the bug fixed in kernel version 4.14?

Could I install this kernel version 4.14 via armbian-config (next-kernel)?

 

Thanks a lot for help.

According to some discussions and tests this is not enough, A64 timer has worse problems so this was posted on the linux-sunxi mailing list recently. Though I think I've read in IRC logs that even this is not 100% reliable.

And somehow Maxime decided to blame us for not reporting the clock issue, even though it was discussed on IRC several times and we here don't have a perfect understainding of arch timer vs system clock correlation.

Yes, I've seen that too. Maxime should not blame us, we only faced the issue and in my case, adding this erratum to config worked without any additionnal patches, I've never face the issue again, but that is maybe only luck ...

If newer patch is better, we can probably try to integrate it in Armbian, but it is up to Maxime to ack the patch, not us ;)

many, many thanks for the quick responses and please excuse my bedelayed answer.

 

In my current version (with kernel 4.13) CONFIG_FSL_ERRATUM_A008585 is not set.
The updated kernel (4.14) results with
CONFIG_FSL_ERRATUM_A008585 = y

Thus, I will upgrade my existing devices to the new kernel (and hope that the issues zador.blood.staine addresses will not occur to me).

 

With my test device I realized this with the tool "armban-config". Is there a way to parameterize the "armban-config" tool to run the update via script or is it possible to do the adjustment to the next kernel via command line?

Is it correct to install the kernel with the following command:

apt-get -o APT::Status-Fd=4 -o APT::Keep-Fds::=5 -o APT::Keep-Fds::=6 --reinstall -o Dpkg::Options::=--force-confdef -o Dpkg::Options::=--force-confold -y -qq --no-install-recommends install linux-image-next-sunxi64 linux-headers-next-sunxi64 linux-u-boot-pine64-next linux-xenial-root-next-pine64 linux-dtb-next-sunxi64

(found in the history.log of the updated device)

 

A test on a device with the kernel 4.13 shows no error and results in the new kernel 4.14.

I have some pine64 with kernel 4.14 and so far the time-problems did not occur with this kernel.

 

Unfortunately, however the pine64 updated  to kernel 4.17 again show the the problem! Time jumps to the year 2113 (and sometimes even to 2208). I use kernel 4.17.5 and 4.17.6. The flag 'CONFIG_FSL_ERRATUM_A008585' is set (CONFIG_FSL_ERRATUM_A008585=y).

 

Thanks a lot for help.

Did you built image beofre or after this commit : https://github.com/armbian/build/commit/556b3067086266dd264e3f5e2dcdf61b60468d27

BTW, you can fix your image manually by editing the DT.

I did the upgrades form an older image with 4.13-kernel via

      apt-get  install linux-image-next-sunxi64 linux-headers-next-sunxi64 linux-u-boot-pine64-next linux-xenial-root-next-pine64 linux-dtb-next-sunxi64

on the 13th of july (resulting kernel 4.17.5) and on the 17th of july (resulting kernel 4.17.6).

When was the commit entered into the next-branch?

 

Can I fix the error if I make an upgrade (apt update, upgrade) to the current image?

My own commit on DEV was on July 13th, but then Igor did a big branch management to switch from old NEXT to new NEXT on July 17th, so maybe the patch got blinded during few days.

So if I update the two devices to the current image (apt update/upgrade), then the error should not occur. I will try it.

As I said previously, using the Freescale errata helps, but it is still not 100% reliable.

And A64 specific fix is still not complete and is not present in Armbian patches.

I know it's an old thread but I just got this problem (date was in 2114) with a recent dev kernel. The symptom was strange -> my DHCP server won't give my Pine64 an IP due to the date difference.

 

I think the patch from Samuel Holland (https://groups.google.com/forum/#!searchin/linux-sunxi/pine64$20timer|sort:date/linux-sunxi/b27QfJJroR0/tZgFFQeCBAAJ

was not applied (or I did not find it)  so I'll try to build a kernel with it.

I can see that the when date attempts to make the clock_settime syscall, it receives EINVAL back.  I'm wondering then why it sees CLOCK_REALTIME as invalid.  I could potentially see an issue with CLOCK_REALTIME_COARSE which  man 2 CLOCK_GETRES says is "architecture specific", but this one is throwing me of.

Also curious, 1551794590 seems to be the last time at which the system clock may have made a checkpoint via systemd-timesyncd on a previous reboot before going back to the future.  B)

 

$ date --date='@1551794590'
Tue Mar  5 06:03:10 PST 2019

 

And a snippet from kern.log showing the current boot time:

Mar  5 06:12:58 string kernel: [    0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034]

I'm also seeing this behavior on a sopine that I recently deployed. It's seemingly inconsistent as well.

 

I checked the kernel config and it appears the CONFIG_FSL_ERRATUM_A008585 is enabled

 

cat /boot/config-4.19.38-sunxi64 | grep -i CONFIG_FSL_ERRATUM_
CONFIG_FSL_ERRATUM_A008585=y

 

And it's a very recent Arbian as well.

4.19.38-sunxi64 #5.83

Short of tracking the date every minute or so in something like Monit to fire off a reboot... does anyone know of a practical work around?

Hi KemoNine,

unfortunately, the problem still occurs sporadically for me (kernel 4.17).

 

I have not found a solution and would also be very grateful for a practical work around.

[my current work-around: "systemctl restart ntp"]

I ended up deploying monit to track and respond to the clock jump. I ended up telling monit to reboot the system whenever the clock jumps ahead too far to keep some of my services I have deployed happy. At the link below you'll find my monit config file for the time jump as well as a small python script that's run by monit to look for any time jumps over 3 months into the future. You can tune the python script to look for larger jumps as well as the monit config to restart ntp instead of performing a full reboot.

I hope this helps even if it's a rough work around.

Fix should already be a part of Armbian NEXT 4.19.y kernel.

Yes that fix should already be part of the existing kernels, however there are actually several timer-related issues on the A64 and it is not clear that they are all addressed even upstream.

 

Even with all of the fixes that have been published I still see the issue recur occasionally.  There is a thread in the Development section where this is (or was) being discussed.

is there any news about this A64 problem? it keeps happening, and makes my pine64 completely unreliable

To my knowledge, it has been fix with the above patch months ago ...

Which image are you using ?
