Still seeing breakage with the e1000/NAT. Now the problem isn't so much that the bug exists, but that unlike in -rc1-mm2, the trace scrolls over and over and over (with some variation down into it) until the kernel completely panics and the box has to be rebooted. http://www.ussg.iu.edu/hypermail/linux/kernel/0607.1/2689.html from Herbert Xu talks about the original problem. It's a regression from the previous -mm whereby the trace would print out just once.
