Kernel panic - not syncing, can't connect via ssh

[jumbo125]

Hello

Today i have a problem, which i had  sometimes randomly. But today i'm at home, so i can connect the odroid via hdmi port.

 

The error message is:

kernel panic.....

 

sorry, but i only can make a picture from the monitor.

This is the picture:

thank you a lot

Tried current kernel? Edge can break anytime...

[jumbo125]

how can i change the kernel?

i change to edge, because i have reboot problems. but i fixed it with another sd card. 

So, how i can go back to the "current" kernel?

@Werner

which is the current/default kernel?

i have this choices

 

i see there is a new armbian avaible for my odroid c2. 

is it important to change from jammy to Armbian 23.8 Bookworm???

can i upgrade without loose all my datas?

[jumbo125]

i tried to find out, the install-date of each kernel version.... all my log files are empty....

i tried to open all files in var/log/apt... they are all empty

I don't know. Neither do I have such a device nor I am a developer. I can give generic advice only.

Overall you can try any kernel from this list.

Not sure that exactly you mean by this question. However here are two ansers that might be right:

- You cannot "upgrade" from a Ubuntu-based userspace to a Debian-based one since they are incompatible.

- Any userspace (Bookworm, Bullseye, Jammy...) for a board are shipped with the very same kernel package. So hardware-supporting-wise does this not make any difference.

Armbian comes with three levels of linux kernels in general (not all boards support all types).  edge = "bleeding edge" or development kernels, not supported, meant for testing only;  current = the currently supported stable kernels; legacy = either a vendor supplied kernel (often not maintained) or an older stable mainline kernel, generally not supported but provided for testing/compatibility reasons.

 

As @Werner stated above you want to install a 'current' kernel.  In the list you showed, you are only showing 'edge' kernels.  You need to select one that uses the word 'current' where you are seeing 'edge' in the listing.

Okay

How can I get a current kernel.

All kernels in the list have edge
