Seems Ubuntu from Canonical uses a customized kernel where CPU usage precision is improved. But Debian and Armbian use previous CPU usage precision settings?

I could solve the instability problems and I am using the 2.5Gbit port now without having errors and with full speed! changing the swich Flow Control On for 2.5Gbit devices ethtool -K <LAN-device> sg off sudo ip link set dev <LAN device> mtu 9000 using the actual dtb file posted above cp rk3399-kobol-helios64.dtb /boot/dtb/rockchip/ update-initramfs -u nano /etc/default/cpufrequtils ENABLE=true MIN_SPEED=600000 MAX_SPEED=1800000 GOVERNOR=ondemand nano /etc/rc.local for cpufreqpolicy in 0 4 ; do echo 1 > policy${cpufreqpolicy}/ondemand/io_is_busy echo 25 > policy${cpufreqpolicy}/ondemand/up_threshold echo 10 > policy${cpufreqpolicy}/ondemand/sampling_down_factor echo $(cat policy${cpufreqpolicy}/cpuinfo_transition_latency) > policy${cpufreqpolicy}/ondemand/sampling_rate done for i in $(awk -F":" "/ahci/ {print \$1}" < /proc/interrupts | sed 's/\ //g'); do echo 10 > /proc/irq/$i/smp_affinity done for i in $(awk -F":" "/xhci/ {print \$1}" < /proc/interrupts | sed 's/\ //g'); do echo 20 > /proc/irq/$i/smp_affinity done exit 0 nano /usr/local/bin/make_nas_processes_faster.sh #!/bin/sh -e for i in `pgrep "iperf3|smb"` ; do ionice -c1 -p $i ; taskset -c -p 4 $i; done # >/dev/null 2>&1 running as a service

Is there a way to copy the system from sda1 [M2-Sata SSD (2280)] to emmc (uboot) from the running system without losing the configuration? If it's possible, how can I do this including configuring the changes? What is the maximum size for the M2-Sata SSD (2280)? https://wiki.kobol.io/helios64/m2/

Hello, With kernel 6.6.56-current-rockchip64 the audio works correctly: cat /proc/asound/cards 0 [RK809 ]: simple-card - Analog RK809 Analog RK809 1 [HDMI ]: simple-card - HDMI HDMI With kernel 6.12.30-current-rockchip64 the RK809 card is not available: cat /proc/asound/cards 0 [HDMI ]: simple-card - HDMI HDMI How can this be solved ? Thank you so much !
