Hi, Recently I reinstalled system on my Odroid C1+ from older Ubuntu with original 3.10.107 to newest Armbian with kernel 6.12.44. Generally it works quite well but I see a lots of stalls detection warnings in logs: Thu Oct 9 02:00:26 2025] rcu: INFO: rcu_sched self-detected stall on CPU [Thu Oct 9 02:00:26 2025] rcu: 0-....:

Hi, for 2 day i am searching for set a bootlogo on the screen while loading klipper but all i get is the linux text that fly by. I set bootlogo= true in armbianEnv.txt does not help i can't find any other option. There should also be Splash can find any decent information about that either So is it possible to show a logo at booting klipper, if yes is it also possible to change it to custom logo or video because it would be nicer to show a logo or video then al these linux lines And i am not a professional programmer so easy language if possible

Yep, looks like it's about the netplan renderer. I've tried the actual image instead of the one I built locally and even just a reboot is able to reproduce the issue. The main difference is that on the image I built networking was via NetworkManager by default, while the image on the website uses systemd-networkd.

Any news on this subject ? Official Ubuntu is too limited .... I'm thinking to change to armbian my server ..... To install it, does it need a full recompilation ? or is there an img ? where can I find the DTB file for M2 ?
