Ignoring packet error, continuing...

I have forward ported the patch to linux-2.6.32.46 kernel. I was just trying to understand this issue belongs to which of the category ? 1. Is there any issue with Ethernet driver E1000 issue ? 2. Is it belongs to KGDB ? 3. Is there any kernel SMP hang issue for x86 64bit architecture which is fixed in upstream kernel ? 4. None of the above and something else is broken ? Is there any available patch ? any guidance to fix the error in E1000 driver. I will really appreciate your help.
