Thank you. Currently I don't have a serial console but possible I'll try to get it. I suspect that it is a problem of CPU settings, because old kernel had maximum 1.1 GHz and had no problems with booting. Would you please tell me, is the /etc/default/cpufrequtils settings relied to boot, or I should try to change cpufreq-dt driver?
Hi! Armbian_21.08.1_Orangepiprime_focal_current_5.10.60_xfce_desktop sometime failed to boot. No green indicator, and black screen. Tried to decrease CPU max frequency sudo nano /etc/default/cpufrequtils ### ENABLE=true MIN_SPEED=480000 MAX_SPEED=1200000 GOVERNOR=ondemand ### but still failed to boot sometimes. Armbian_5.75_Orangepiprime_Debian_stretch_next_4.19.20_desktop have been installed before and boot fine during 2 years.
