system crashes after sync command

Hi.   My helios64 always crashes with this method :    [environment]  1TB m.2 sata ssd for system  16TB seagate exos on data drive  18TB WD Ultrastar DC550 on data drive  Linux helios64 5.9.14-rockchip64 #20.11.4 SMP PREEMPT Tue Dec 15 08:52:20 CET 2020 aarch64 aarch64 aarch64 GNU/Linux    about 620,000 files on data drive.     [method1]  #sync  #sysctl -w vm.drop.caches = 3  #ls -CFR [datadir] > [tmp dir]  #
Hi, could try to the following tweak and redo the same methods that triggers the crash :   Run armbian-config, go to -> System -> CPU   And set: Minimum CPU speed = 1200000 Maximum CPU speed = 1200000 CPU governor = performance   This will help us understand if instability is still due to DVFS.
