Hi,
we installed Proxmox on two NASes that will not recive Firmware upgrades anymore ("just" an i3 w/ 16GB RAM) an everything works fine. The only problem is that one Interrupts hogs up the CPU.
With
Code:
grep . -r /sys/firmware/acpi/interrupts/
I found out that the culprit was:
Code:
/sys/firmware/acpi/interrupts/gpe12:3232861551   enabled
And running:
Code:
 echo disable > /sys/firmware/acpi/interrupts/gpe12
Fixes that issue. I'm just not sure what exactly thoe general Interrupts represent.

Can anyone shed some light on this for me? Thanks :)
