Odroid XU4/HCx Booting not working, Debian 12 (Bookworm) with OpenMediaVault 7.0 Image

Endless loop booting Image.

• I download Image form source: https://dl.armbian.com/odroidxu4/Bookworm_current_minimal-omv
• Flash Image with Rufus-4.11 --> no problem
• insert sd-card in odroid hc1 --> blue LED is flashing
• I ping to odroid with windows 'ping odroid -t -w 100'  --> replied 10 seconds, then there was no response for 40 seconds, and it repeated, I wait 30 minutes.

• I use Image from archive without OpenMedaivault --> Booting Ok
• I install OMV 7.0 manually described following link: https://docs.openmediavault.org/en/7.x/installation/on_debian.html
• in first view everything seem fine BUT:
  after restart and save settings to SD-card --> odroid restarts after 20 seconds, if you do anything with huge load, it restarts, even 'apt update' or 'apt upgrade"

I did several tests, buy a new SD-card try 3 different cards, remove hard drive remove PCB and renew thermal interface material, nothing helps. I installed it 5 to 10 times and I did the installation in different ways. Also nothing helps.

I  use my old working sd-card and I did some test, it works properly. (old means: installation is 2-3 years old)

I try 'armbianmonitor -m' --> output: 23:30:52   600/2000 MHz  0.66  19%   6%  11%   0%   0%   1%  37.0 °C  0/3

The frequency changes depending on the load, I used stress -c 8 --> frequencey 1400/2000MHz  -> works perfect

I try  Debian 12 (Bookworm) with OpenMediaVault from armbian download page. (Build Date: Jan 19, 2026)

I try 'armbianmonitor -m' --> output: 22:10:52   200/200 MHz  0.66  19%   6%  11%   0%   0%   1%  24.0 °C  0/3

The frequency was always at 200/200MHz.

I think I found the error in '/etc/default/cpufrequtils 

Both values are "0".

MAX_SPEED="0"
MIN_SPEED="0"

I compare it with my old working sd-card. The values there:

MAX_SPEED="2000000"
MIN_SPEED="600000"
 

I Update the Image:

I 'unxz' the image that I had downloaded from armbian page, 'losetup' it, 'mount' the partition and change the value in 'cpufrequtils' to MAX_SPEED="2000000" MIN_SPEED="600000".

I 'xz' the image, flash it to my sd-card and now the images works on my Odroid XU4/HC1 perfect.

Is this a bug?
