critical temperature reached, H3 overheating
Posted: Mon Sep 30, 2024 10:45 pm
Hi,
I have problems with NEO due to Linux kernel overheating shut down, using the Linux kernel 4.14 on Debian Trixie.
The syslog shows:
Teh hours before, the kernel shows above 80°C by:
But there is not much load on it. When looking to "top" I see less then 10% as load average and more then 90% idle. "iotop" shows all processes <1%. And when measuring the chips, all are cool at below 40°C
It looks like the CPU suddenly get into a hot-state above 80°C, because it stays there for hours independent from the process load. Even after a reboot command, the system comes up again and is still above 80°C.
A power cycle temporarily fixes the problem. The system comes up with about 50°C and slowly cools down to about 30°C for the next 1 to 3 weeks. Then it suddenly becomes hot again until shutting down.
Any experiences with this, what helps? Is there a kernel patch available?
