Since I upgraded to Armbian 23.8.1 (Kernel 6.6.31) I cant copy larger files from a CIFS share to a local attached sata disk on my banana-pi. Copy starts and gets stuck at around 4GB of transferred data ... its independant if I use rsync, cp or mv to transfer files. What I can see in the logs directly after the transfer gets stuck: root@nas03:~# dmesg [ 1280.477240] ------------[ cut here ]------------ [ 1280.477276] WARNING: CPU: 1 PID: 4182 at

I am using Orange Pi 5 Plus with eMMC. I tried to install a program I need, but an error occurred saying that installation was not possible because SecureBoot was disabled on the system. So I need to enable SecureBoot, how do I do that? Thank you.

@NicoD do you still have your m4v2 and may verify uart connection and working debug console? thx in advance

Sorry, forgot to mention that you have to plug the male-to-male cable in the OTG port; other ports won't work. That's the maskrom mode. Anyway you can try to boot armbian from sdcard
