There isn't much development into e1000 driver (only few bug fixes) between 3.0.36 and current stable kernel release. So I am not sure if backporting is going to solve the issues. 82540 is old part and in recent years I haven't seen anything like you describing i.e. bad page table entries, out-of-memory panics, etc. Please send the panic message and I will look into it. I am guessing this is system/board specific, right? Or you have similar issues on more than one type of system(s)?
