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:
Quote:
eth0 (rtl8168 (using rtl8169 driver) - Onboard PCI-E Gigabit Ethernet)
eth1 (rtl8169 (using rtl8169 driver) - RTL8169 PCI Gigabit Ethernet)
The chipset running the IDE drive that experiences the DMA crash is:

If you guys need any package versions just ask. Also feel free to point

HELP! I want to be able to multihome but this is stopping me :(

^^^^^^^
Do you mean the in-kernel r8169 driver or Realtek's one ?

The second (PCI only ?) network card is plugged and lspci does not display
it, right ?

Please send a complete dmesg from boot and the content of /proc/interrupts
once the link is brought up.

It is suggested to send network related problems to netdev@vger.kernel.org

Well it seems I have solved it by disabling APIC and MSI/MSI-X
interrupts. Both NIC's up and playing nicely.
Now just to figure out why it's not communicating with anything...
Thanks Francois!

How can we tell that the nic are playing nicely if they are not
communicating with anything (i.e. no change in the rx / tx packets
count nor in ethtool statistitcs) ?
It is a bit confusing.
