High CPU usage

[gallaics]

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:

pfSense 2.4.4
Gigabyte J4005N d2P motherboard with the latest BIOS
(Built-in Intel Celeron J4005 (up to 2.7 GHz) dual-core processor)
WD green M.2 Sata SSD
2X4GB DDR4 Kingston 2400 memory modules
INTEL PRO/1000 PT Dual port PCIe NIC

Hmm, weird.

How does that appear in ps -auxww ?

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
