it seems that qcom-wdt is now properly keeping the watchdog maintained, so hopefully that is the end of my woes and i can just enjoy a stable machine with EL2 and 64GB RAM
also maybe it would be nice if lenovo just updated gunyah (there has been a fix for like 9 months now from qualcomm) in the next firmware update. but as far as they are concerned this is a windows on arm laptop and they do not care about linux, it seems.
