Hello! We have a server with a Supermicro H8DGi-F motherboard. This motherboard has two 4x PCIe slots. Next to the ports on the motherboard is written "(PCIe 4x in 8x)". We have Intel and Supermicro 4-port PCIe 8x ethernet adapters. Whenever an adapter of either manufacturer is inserted into one of the (PCIe 4x in 8x) ports, the FreeBSD 8.1 and 9.0 kernel panics on boot with: panic: Couldn't find an APIC vector for IRQ 14 Putting the adapters into any of the other ports (8x and 16x) has no issues. Just to make sure it's not a hardware issue, we booted into Linux, and the adapters work fine in the 4x (in 8x) PCIe ports, with large transfers performed through them. FreeBSD has been upgraded to the latest binaries. Do you have any suggestions to us, and/or do you require any more information? Please reply-all so I can see your reply as I am not currently on the mailing list. Thanks! Iordan Iordanov
