Random reboots since upgrading from Core to Scale

I saw your other posts in a thread with similar issues.

It is true that the background load of 24.10 is lower than previous versions.
We have seen processors that are poor at moving from low power mode to full performance mode.

Linux enables low power mode through control of C-states… so it is possible that BIOS settings may need to be tweaked.

I don’t know if this is the issue, but found some links:

C-states.md

To limit a CPU to a certain C-state, you can pass the `processor.max_cstate=X` option in the `kernel` line of `/boot/grub/grub.conf`.

Here we limit the system to only C-State 1:

~~~
    kernel /vmlinuz-2.6.18-371.1.2.el5 ... processor.max_cstate=1
~~~

On some systems, the kernel can override the BIOS setting, and the parameter `intel_idle.max_cstate=0` may be required to ensure sleep states are not entered:
