First of all hi to everyone, and apolgies in advance, since this is my first post here.
I'm having a strange problem with my DX58OG. The PRO/1000 PT Quad Port Server Adapter disappears every other boot.
On cold startup, card is detected and works as expected, reboot and it's gone, reboot again and it's there as if nothing happened.
I have another machine, same motherboard, but with a dual port adapter, and works every time.
Bios is the latest SOX5820J.86A.0888.2012.0129.2203.
OS y CentOS 5.8, with a custom kernel, based on CentOS 6.2 kernel.
The strangest thing is that it's not even listed by lspci, it's like the card is not there.
Tried booting with pci=noacpi, pcie_aspm=off, disabling aspm from bios, and many other things but nothing worked.
Does anyone have any suggestion?
Thanks in advance.
I don't remember the exact model of the PowerSupply, but it's really good, kind of "Gamer" suppy.
lm_sensors doesn't detect anything in this mother, but I took these from the BIOS:
One more thing, I can't confirm, but I'm pretty sure that using an older bios (876), I had to unplug the machine for the card to appear. It changed to "every other boot" in version 888. Also version 888 changelog mentions something about "quad port" cards, but for windows.

8086:10cd is the Onboard.
8086:10a4 is the card with problems
Well, old Intel quad port adapters are actually combination of two dual-port adapters, linked via PCI/PCI Express bridge, like dual-GPU graphics cards. And this solution lead to incompatibilities - http://www.intel.com/support/network/adapter/pro100/sb/CS-030873.htm
Try to search for "Force Gen1" option in MB BIOS Setup, this will force PCIE v1.1 protocol to all 2.0 slots and likely solve detection troubles. Of course, videocard will be also affected, but if it is not top-level 'iron', you will loose really nothing in terms of performance.
Seems like this option isn`t available in Intel BIOSes, although other vendors (like ASUS) have it. May be this option still supported by BIOS, but hidden in Setup, Intel Integrator Toolkit utilities may bring it back to light by editing & reflashing BIOS, but this too much efforts for making buggy controller work.
