Interesting Boot failure on HEAD with a large number of IGB nics

[Mark Saad]

All
 I am wondering if anyone has run into this issue before , and if there is
a fix.
I have a Scalable Informatics siRouter with 24 Intel I350 igb nics and 8
intel 82599ES ixgbe/ix nic . The SiRouter is a Supermicro X9DRX+-F with a
bunch of intel nics.

On Head I run into a boot panic out of the box while plumbing the usb
controller . The box crashes with

ehci0: <Intel Patsburg USB 2.0 controller> mem 0xdd923000-0xdd9233ff irq 16
at device 26.0 on pci0
panic: Couldn't find an APIC vector for IRQ 16

However it has only probed 8 of the 24 igb when is crashes. Here is the
complete boot up with some additional info.

Now the interesting thing.

 DragonFly 4.2x boots fine  see the dmesg here

OpenBSD boots and finds the nics as well see dmesg here
http://dmesgd.nycbug.org/index.cgi?action=dmesgd&do=view&id=2777

NetBSD Pukes while probing something out of the box and I cant get the
serial console to work.

Linux 2.6 CentOS 6.6 works

OmniOS / Illumos-gate and Illumos-joyent work out of the box



So my goal here is to make the box boot FreeBSD . It had been used prior
running OmniOS and CentOS and well now I want to make it work. :)

Any ideas here ?
