Since I got my Helios64 : I had an hadrware problem (voltage on some disk drop too low : it ended : replace MB) But I had many panic/ freeze since first days. I was never able to pass 10 days without problems until I read this topic : Last month I decided to set freq policy as read here : root@helios64:~# cat /sys/devices/system/cpu/cpufreq/policy*/scaling_max_freq 1416000 1416000 root@helios64:~# cat /sys/devices/system/cpu/cpufreq/policy*/scaling_min_freq 1416000 1416000 root@helios64:~# cat /sys/devices/system/cpu/cpufreq/policy*/cpuinfo_cur_freq 1416000 1416000 And I have a much more stable system root@helios64:~# uptime 18:35:42 up 30 days, 1:34, 1 user, load average: 0.01, 0.03, 0.00 root@helios64:~# uname -a Linux helios64 5.10.60-rockchip64 #21.08.1 SMP PREEMPT Wed Aug 25 18:56:55 UTC 2021 aarch64 GNU/Linux root@helios64:~# cat /etc/issue Armbian 21.08.1 Buster \l

UPDATE : Slot 1 & 2 won't start anymore with many tests : Battery connected or not doesn't change anything I tried with external power and brand new sata 6Gbit cable : it's working fine I tried with sata power splitter Y from Solt1 or slot2 line : disks doesn't start with external Sata cable : It seems there are trouble with power lines from stock harness I tried with sata power splitter connected from Slot 3 powering slot 1 & 2 : drives 1 / 2 / 4 / 5are working : seems OK I will try with 2 sata splitter Y (delivery planned for tonight) Conclusion for now : Seems power isn't properly achieved through stock harness : I was thinking trouble with sata data cables but problem for my unit seems mainly from power sata connectors I will keep you update
