[Bug 347711] Re: Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller Unstable on Jaunty

I have the same problem on my Asus EeeBox:

 - processor from /proc/cpuinfo: 
  Intel(R) Atom(TM) CPU N270   @ 1.60GHz

 - network controller from lspci:

04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)

Here is a slightly different backtrace from a more recent kernel
