I have problem, my screen show this message usig pfSense 2.1 BETA 64 bit

This usually means something is interrupting on irq16 and there is no interrupt handler for it.

It will probably be worthwhile going into your BIOS and (if possible) disabling unused devices such as audio device(s).

@mhby87:

I presume you mean pfSense 2.0.x RELEASE; pfSense 2.1 RC0 has only just been made available which means 2.1 RELEASE won't be available for a while yet.

Since one of your NICs is on irq16 it is not good to have irq16 throttled.

Opps, typing error, that pfSense 2.0.X-RELEASE ;D

Using command vmstat -i, show irq16: ste0. ste0 use for TP-Link 10/100M Network Card (IT-P), This interface is functioning.

I, try to disabling unused devices and see the result tomorrow.

Thank you.
