Comment 1 for bug 746914

To follow up: using the Intel PCIe NIC instantly solved all my problems. No more lockups under combined network and PCI load. I won't be going back to Realtek NICs ever. (If someone can point to a specific purported bugfix that's in some kernel I can simply download and install without building my own kernel, I can try this on my hardware to test the bugfix, but I'm not going to bother for the case of, "It's a random new kernel but nobody's specifically addressed this bug, but test it anyway.") I'm currently running Natty as of 4/8, which is using 2.6.38-8 under AMD64 desktop on a 6-core CPU.
