I think I got the same or similar issue with a banana pi pro.   I used the board about a year with the latest bananian os without an issue, rock solid, uptimes up to 1 month (then planed shutdown for backup image of the sd card). 2.5" hdd attached through the SATA port. Now I migrated to the latest 5.38 debian with mainline kernel . Output of armbian-monitor -u here: http://ix.io/Fpe   Sporadic "freezes" - after just one hour runtime or (max for now) 14h.
