Thanks for answer. Yep, I installed standard image. Since I was using two storage devices (SD and MMC), I first noticed issues with the mounted file system on the SD card, which I eventually had to remove (only the MMC storage remained). Then I noticed errors causing the processor to freeze, which got me a little worried. It was long time ago when last time I was compiling Linux kernel (FreeBSD more recently) , but maybe I will try to follow your instructions and try to do it. Many Thanks

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-....:
