NanoPi Neo2 login stuck past entering user/password after Update

[guidol]

Today I did update my 3 NanoPi Neo2 via apt update/upgrade, but only one is accessable via ssh after the update.

(without SSH/SSL-conect also no conection via SFTP/WinSCP because if the timeout)

The one which is accessable has after the update 

Welcome to Armbian 23.02.2 Bullseye with bleeding edge Linux 6.7.12-edge-sunxi64

( Machine model: FriendlyARM NanoPi NEO 2)

 

The two other do show prompts for user/password but doesnt login via ssh - and after some time they time out and I can reenter user/password

After connecting via TTL-serial I can also enter user/password and then the Neo2 shows me:

After prssing Ctrl-C:
^C
Armbian 23.8.1 bullseye ttyS0

npi-neo2-24 login:



For non-existing users I do get a timeout at the serial-TTL-Port:

npi-neo2-24 login: maxandmoritz
Password:

Login timed out after
Armbian 23.8.1 bullseye ttyS0

npi-neo2-24 login:

 

but nothing more - and this time the login doenst time out.

 

But the armbian seems to boot up correctly, because the SAMBA-server on the Neo2 is available/useable.

 

So the only way to change something in the system will be to make modifikations to the SDCard - but which change have I to do?

 

Maybe its something between the Neo2 Revisions 1&2 (not/no Black Revision).

 

Does anyone got a glue/idea for me?

 

Thanks in advance

I dont know was it was - with updated armbian (with Kernel 6.7.12-edge-sunxi64 or 6.6.31-current-sunci64) I do get a high cpu load and couldnt login anymore.

 

Because of the CPU load the temperature gets high as 73-89 degree celsius

 

Because I could login or find a error (maybe the installation is too old or too mich times updated) I didi go the way of fresh install, but had to avoid to much kernel/firmware to kernel 6.6.31-current-sunxi64....

 

So I ended in reinstalling all my 3 Neo2 as base-system with

Armbian_23.11.1_Nanopineo2_bookworm_current_6.1.63
(latest full cli-image for bookworm for download)

 

After initial setup (user/passwd/timezone) I did freeze kernel/firmware in armbian-config.

Then updated via apt update/upgrade to 
Welcome to Armbian 24.5.1 Bookworm with Linux 6.1.63-current-sunxi64

With that my 3 Neo2 do work stable at 43 degree Celsius (when my room is at around 29 degree celsius) - like it was before the critical update.

 

because they are mostly samba-servers (in theit siler aluminum-case) it should'nt be a problem to use only this kernel.

When it works - it works - never change a running system
