Hi All,
The issue I am having is when bringing up a second ethernet interface that uses the rtl8169 driver, it seems to cause network issues. I lose all network connectivity to the machine, and I simultaneously see a DMA error occur for my primary IDE drive.
Two interfaces:

The chipset running the IDE drive that experiences the DMA crash is:

It was historically impossible to have 2 identical nics on the same bus. I am sure there is a solution, but I would start there.

They are not identical as such, as one is a PCI-E 8168, the other a PCI 8169. Unless you mean two NIC's using the same driver module? Thanks for the suggestion though.
I've actually just found the official rtl8169 driver on Realtek's website, so I'm going to give that a go.

And I've fixed it, by disabling APIC and MSI/MSI-X interrupts in my kernel.
Now to figure out why it's not communicating on the new network
