Issue with Linux watchdog timer where system did not restart for NUC8BEH

Hello,

We are an iot company using nucs in our products.

Currently with the BOXNUC8i5BEH1 we have problems with the watchdog with ubuntu 20.

Initialization seems all fine but it never restart. 

iTCO_wdt: Intel TCO WatchDog Timer Driver v1.11
iTCO_wdt: Found a Intel PCH TCO device (Version=6, TCOBASE=0x0400)
iTCO_wdt: initialized. heartbeat=30 sec (nowayout=0)

We already reported this issue in the forum and was fixed for another model (thanks again for that) https://community.intel.com/t5/Intel-NUCs/Issue-with-Linux-watchdog-timer-where-system-did-not-resta...

 

Attached is the report from the  Intel® System Support Utility.

 

Thanks in advance!

Hello mgiachetti,  

  


Thank you for posting on the Intel® communities. I am sorry to know that you are having issues with your Intel® NUC Kit NUC8i5BEH.

  


In order to better assist you, please provide the following:


1. Did you notice the same issue with Windows 10 or Windows 11?

2. Was the unit working properly before?

3. When did the issue start?

4. Can you provide more details about the issue?

Hello Deivid,

 

1. Did you notice the same issue with Windows 10 or Windows 11?

We didn't test this on Windows. We only use linux in our product.

2. Was the unit working properly before?

This never worked in this unit or any other NUC8 we have in stock. Same happened to us with NUC10 but was fixed with a bios update after post the issue in this forum.

3. When did the issue start?

We notice this a few month ago. But before that we weren't using the watchdog.

4. Can you provide more details about the issue?

Yes, we have the same issue as this two post, only different NUC models.

Thanks Deivid for the quick response.

Hello mgiachetti, 

 

 

Thanks for the information provided. As a test, please perform a BIOS recovery with the security jumper.

Hello Deivid,

I followed the steps to update the bios (it was the same already installed) with the same results, the watchdog is not working.

Thanks.

Hello mgiachetti, 



Thanks for your patience ad time. We are releasing a new BIOS version for Bean Canyon scheduled for WW41.

Please let me know if this is fine for you.

Hello Deivid,

 

Thanks for the quick response. Is there any chance to get a firmware to test earlier? We reporte this same issue for the NUC10 too and the fix took less than a month. We have a lot of NUC8 equipment in our customers hands with this issue and having an equipment that stops working is a really bad experience for an IoT product.

 

best,
Martin

Hello mgiachetti, 



I will send you an e-mail to the e-mail address associated with your community profile with a DBIOS.


Please, be aware that this BIOS is a testing version and should not be shared with other people.

Hello Deivid,

Using the testing firmware still doesn't work for me.

It's not recognising  the watchdog and dmesg is only showing this line:

When it works it shows something like this:

iTCO_wdt: Intel TCO WatchDog Timer Driver v1.11
iTCO_wdt: Found a Intel PCH TCO device (Version=4, TCOBASE=0x0400)
iTCO_wdt: initialized. heartbeat=120 sec (nowayout=0)

 but still no luck.

Thanks

Hi Deivid

 

Were the developers able to come up with a fix? We also are facing similar issue, where the iTCO watchdog is detected and enabled, but the counter does not count down.

We have hundreds of such devices in the field and currently someone has to  visit the premises and manually cycle power. Please help.

I see that the fix for NUC7i7DNBE read "Fixed Watchdog timer issue with Ubuntu Linux". Are these problems only on Ubuntu linux. Will a different linux  distro work?
