The patch did prevent the whole system from crashing but I have to unplug and plug something like 20 times to get it not to spit out those error messages. Even once it is up, it doesn't operate at full gigabit speed and there is something funky going on. When sending via scp it maxed out at 36MB/s and there was some kind of issue when recieving, transfers stalled unless I disabled TSO and even then maxed at 20-21MB/s. True though that it didn't crash the system when it was beforehand. I'll double check it again on 3.12. Hopefully someone with the same motherboard as me can test, or at least someone with a AMD FX system to see if my nic is faulty or i'm doing something else wrong.
