Energy-saving mode kingston A2000

Post by aes4096 »

Good morning. I put together a server on ubuntu. My problem is that it seems to me that my NVMe goes into hibernation and the server boots into the BIOS. This can happen after an hour of work, or after 1-2 days of work. Everything is arbitrary. It seems to me that this could be a problem in Ubuntu or in the BIOS. If the problem is in the BIOS, then I don't quite understand what needs to be configured in it in order to remove the NVMe from the energy-saving mode. If you insert Samsung 860 evo sata 3 instead of Segeate, then there is no problem. But I need more disk space. I put nvme in a stationary PC running Windows 10 - it works perfectly there. I really hope for your help.

Server Specifications:
Motherboard ODROID H2+, RAM 16 Gb Samsung (2 x 8 Gb), M.2 NVMe Kingston A2000 SA2000M8/250G, HDD WD Red 4Tb, HDD Segeate 2Tb, OS Ubuntu 20.04.2

We've run a few H2/H2+ servers with NVMe storage 24/7 for a couple of years.
But there was no such issue so far.

Can you tell me which symptoms make you think about hibernation or energy saving mode?
Which power supply do you use?
Was there any syslog to find a root cause?

Maybe there is some dmesg message when it hibernates. Try leaving a dmesg -w running.

i'm use 15V/4A power supply EU plug.

In fact, I'm not exactly sure if the NVMe goes into hibernation or power saving mode. I come to such conclusions when I try to find a similar problem in Ubuntu operating systems. The symptoms are very similar to those described in AskUbuntu. The solution proposed on AskUbuntu did not work for me or I did something wrong.

I haven't reviewed the syslog yet. I will study later.

Perhaps it is worth trying a combined solution to the problem on the part of Ubuntu and in the BIOS, since the proposed option is on AskUbuntu and here? How to determine which Port number is assigned to m.2 NVMe?

You can disable all 6 PCIe ports' de-emphasis option.

BTW, I found a couple of users reported compatibility/stability issue with Kingston A2000 storage devices.

"You can disable all 6 PCIe ports' de-emphasis option." - Thanks, I'll try again. Today I turned it off for all 6 ports - it did not help.

"BTW, I found a couple of users reported compatibility/stability issue with Kingston A2000 storage devices." - Yes, I've seen these topics. I've been trying to solve the problem for a month :D :D :D :cry: :cry: :cry:

My ssd seems to be out of order. odroid h2+ freezes on motherboard logo splash screen. The situation is similar with my stationary PC. Also when I tried to install ubuntu it was written that ssd is no longer writable.

Can you please tell me if this model will be more compatible with Odroid H2 + - SSD M.2 Samsung 970 EVO Plus [MZ-V7S250BW]?

Many people reported Samsung EVO and EVO-Plus NVMe worked well with H2/H2+.

Goodnight. I installed NVMe Samsung 970 EVO Plus three days ago. Since then I have not experienced any problems with the transition to hibernation, etc. I think the problem may be in general with NVMe Kingston. It would be nice to make a list of supported NVMe on the official Wiki so that other people don't have problems.

The topic can be closed. Thanks for the help.
