So what to do in order to have a stable situation ?!
Quote
I installed armbian 20.08.21 with kernel 5.8.17 (and neither 5.8.14 nor 5.8.16 ), and i've just encountered the whole system being frozen (during a MDADM RAID5 array creation / after ~20h of rebuild ...), hence the need to power-down the NAS (first led was blinking red).
Linux helios64 5.8.17-rockchip64 #20.08.21 SMP PREEMPT Sat Oct 31 08:22:59 CET 2020 aarch64 GNU/Linux
I don't have any logs (as by default journalctl is persisted in ram) so i have no clue about what has happened (nothing in kern.log), but could this be linked to the issue described in this post ?
Or was this identified kernel crash only happening on 5.8.16 and is now corrected with 5.8.17 ?
So should i stay on 5.8.17, or is it adviced to revert to 5.8.14 ?

And today i just got (but without immediate freeze and without blinkind red light / but i still had to reboot after a few minutes due to weird behaviors, and even if ssh sessions were still online) (still with 5.8.17)

So what to do to have a stable situation ?
Is it only possible ?
With which kernel ?
It seems to be "under load" (one freeze during RAID array being built, and several ones (with .14 or .17 kernels) while files were being copied through the 1Gb/s network interface).
- System newly installed and running on fresh SSD card.
- 5*3.5" WD HDD plugged in / RAID5 mdadm array (so no M.2, ...)
- nothing else done on the NAS (nothing has been installed on the OS, no processes in memory outside raid + rsync or scp file copying through SSH)
