PfSense cannot detect NIC on re-powering up

  • pfSense 2.3.1-1

    Here's the hardware: Aaeon GENE 9455 Rev.b (

    pfsense seem to lose one of the NIC when its powered off, then on again. It was able to detect only 1 NIC, but not both.
    I had to restore factory defaults for it to work, but only for that one instance. If i "halt" the system (then power off for the move into closet), and power up again, it says I have only 1 NIC.

    Any ideas?

  • Hi all,

    I've narrowed down to this. seems like BIOS is randomly not assigning IRQ. Anyone have any ideas why this could happen?

    See screenshot:

    Note the 2 NIC, then 1 NIC in another.

  • It's a hardware issue of some sort. Maybe a BIOS bug, or the NIC might be flaky. I'd look for a BIOS update.

  • Thanks cmb,

    seems like this board is obsolete and no bios updates are available..

    guesss i'll start looking for new hardware…
