High CPU usage
-
Hi guys, it seems like I'm running out of ideas what causing high cpu usage ~65%-75% by default with a minimal traffic passing through.
I'm new to pfSense | FreeBSD and any help appreciated in advance.Here comes some info about my fw:

Hi Steve, it seems like this motherboard and pfSense ain’t friends at all, acpi issues all over the place... I tried to turn it off in loader.conf but then it just doesn’t boot. I’m going to replace this board with a different one and give it a go.
Thanks
C
