Rock64 crash - spinlock lockup suspected on CPU (possibly thermal reason)

[JoeH]

Hi, I often get an error spinlock lockup suspected on CPU#X where x is cpu core number from 0 to 3, one after another. When that occurs in terminal everything freezes and the only way is to reboot the device using force poweroff. It's popping up only under stress (at least 30-50% of all cores) in Chrome for instance. I'm using a 13x13x10 mm radiator with average quality thermal paste. Temperature is about 50-65 Celsius degrees. I'm using latest Ubuntu Artful build. Is it possible that it's caused by thermal issue? Hardware Issue? Or maybe it's because unstable distro?


Please go easy on me, I'm rather beginner.
