Thinkstation P620: random crashes - Lenovo wants me to send it in :-(

2021-09-08, 20:16 PM

I get random crashes and the code is S202 (system voltage and power - internal CPU error cased a system reboot). I ran a system test which didn't identify a problem.

 

I have paid for on-site support support but Lenovo says that I have to send it in:

"Please be advised that in order for us to arrange on-site repair, we need to identify the faulty parts.
Based on the problem description and the diagnostics, we do not have sufficient information to determine what part might be faulty.
Additionally, we can only dispatch one part per issue.
This being the case, to ensure resolution within single repair, we can collect the device and investigate the issue.
Please confirm if you wish to proceed."

 

None of what is being said in the above is said anywhere I can find on the web site (e.g. can only despatch one part per issue). I am beginning to feel that I am being taken for a ride here as Lenovo seems to only want to send someone out to swap out a part rather than a real engineer who can test, diagnose and fix. 

 

This is my first Lenovo workstation and my Lenovo laptop never had an issue. So, am I being unreasonable here or  am I being taken for a ride...? Oh and it has the corrupted back-up BIOS too!

Unfortunately, an S202 diag error is a critical error where something is likely causing the CPU to lock up and reboot the system unexpectedly.  Can you give us a few more details on your P620 setup? 

 

- P620 configuration? 

- Operating System used? 

- BIOS version? 

- SIO/EC version?

- Nvidia driver version?

- What type of workload are you doing on the system whenever you see the S202 diag error?

Sometimes I am doing nothing on the system and it crashes, yet it can go for 8 hours or more sometimes without crashing. IT nearly always crashes when I am rendering large 4K GoPro files to MP4 of around 100GB. This uses all the cores for a number of hours. 

System specification: (30E0CTO1WW)

AMD Ryzen Threadripper PRO 3955WX 16-Cores 

AMD Radeon RX6800 (PCIe 4.0 and 16GB RAM).

64GB RAM

Hard drives: WDC WD120EMFZ-11A6JA0 12GB ; WDC WD80EMAZ-00WJTA0 8GB hard drive

NVMe drives: Samsung 980 PRO 1TB; Samsung MZVLB1T0HBLR-000L& 1TB.

Was on Windows 10 but due to the problems upgraded to Windows 11 to see if that would help.

Bios: S07KT22A (but that has corrupted the back-up BIOS)

AMD Radeon software 21.6.1 (most up to date released version). 

 

I already cleaned the system of Radeon software and reinstalled.

Many thanks

One of the things that could be causing the system to crash would be the AMD Radeon RX6800 graphics card.  Unfortunately, this GPU isn't supported in the P620 and we have no idea how it would operate within the P620 system.  What GPU did the system come with? Is it possible for you to swap out the GPU to a supported GPU to see if the system would crash then? 

 

As for the recovery BIOS corrupted issue with BIOS S07KT22A, this can be fixed relatively easy.  Here are some quick step-by-step instructions on how to fix that issue: 

 

1. Unplug AC power from the system.

2. Move JP55 jumper (located next to the onboard LAN port on the motherboard) from pins 1-2 to 2-3. 

3. Re-plug AC power and Re-flash BIOS S07KT22A.

4. Unplug AC power from the system and move the JP55 jumper back to the original position.  

5. Re-plug AC power and the BIOS Recovery SPI should be fixed.

I swapped the RX6800 card out for an RX570 and the system did over 18 hours without crashing. Doing some more testing today.

 

The RX6800 was the only card I could get at the time and that had enough on board RAM to do what I needed. I don't understand why might not be compatible.   The only compatibility I have had to worry about previously was physical size and enough power connectors - all of which is fine on the P620.

 

Thanks

Just for awareness, the AMD RX570 is another unsupported GPU.  However, briefly looking up specs of the two cards you have, it appears that the RX6800 is Gen4 versus RX570 is Gen3.  This could be the driving factor of why the one card is failing over the other card.

Thanks for your response - much appreciated. I am new to workstations, so I am puzzled as to why there would even be an issue - I have moved graphics cards between PCs over the years with very few issues - most were solved by completely uninstalling the software and reinstalling. Yet this issue is not solved by doing that...

 

Many thanks

Well, the issue here could be a Gen4 versus Gen3 signaling issue.  The first GPU you tried was a Gen4 GPU which "crashes" the system.  The second GPU you tried was a Gen3 GPU which seems to run OK.  On an unsupported GPU, this will be very hard for us to try to debug remotely. However, if it was a supported GPU, then this would be something we can help debug better.

OK thanks. Anyone with some concrete troubleshooting advice for me?

 

Many thanks,

My suggestion is to let Lenovo Service/Support help to support you with this case.  S202 errors are not something that is easily debugged in the field, and not something that a field technician would really have the skills or tools to attack in a field setting.  

 

I'm not affiliated with that team, but my guess is they would potentially need to consider replacing both the motherboard and CPU in order to attempt to resolve this error.  From the feedback you provided earlier, it sounds like they might limit their field techs to replacing a single part during a service call (I've actually not heard of this before, but can't really confirm/deny that this is normal practice for that team).  So it sounds like they prefer you send the full unit in to be serviced as opposed to (possibly) creating multiple service calls.  

 

Your best bet would be to call Service/Support and work with that team directly to try to get this issue resolved.   Unfortunately, there is not much we're going to be able to do from the forum side to help debug that issue remotely due to the nature of the trigger for that error code.  I don't think that team is trying to "take you for a ride" as their goal is to help get the problem resolved for you, but I think you're certainly valid in bringing up the fact that you expected to be covered with onsite service.
