Hi,
It's running with Armbian Brookworm build by me with official script.
Two different crash arrive, one with fault led red system flashing, second with all blue led are fix, lost network and lost console access with usb-c cable.
In log, they are nothing important, crash append but i not found information in log (My log isn't in ramlog, i disable this shit feature...).
I have 4 8TO raid 10 with BTRFS over Luks, i reproduce crash by run btrfs check file system with checksum and mdadm check raid at same time.
My brother have helios64 and he crash his Helios simply crash on waiting with docker container active and do nothing and without any HD drive with all last official Kobol Armbian build or with my own build.
I will test next week with this image system (https://dl.slarm64.org/slackware/images/helios64/) simply to know if armbian specific problem or hardware problem.
Have a good day.
