I have strange issue with NIC 'Intel Corporation 82574L Gigabit Network Connection' which is propably integrated in a intel atom motherboard (kimsufi atom).

After I boot a kernel, gentoo-sources 3.9.5, NIC does not respond for about 4 hours, ping neither ssh works. I can boot rescue system there, tunnel over ssh the /dev/sda (nbd) and boot it in qemu-kvm here with no issue, so I know it boots just fine, also the uptime is over 4h as soon as I can get in there. Kernel is absolutly minimal (started with make allnoconfig) so there is no weird drivers and such. After boot I can see in dmesg:

[14600.643213] nf_conntrack: automatic helper assignment is deprecated and it will be removed soon. Use the iptables CT target to attach helpers instead.


And I have no idea what's wrong, the rescue system use 3.8.3 kernel and I can access it as soon as it boot. I have absolutly no idea wtf is going on here.

edit: reproduced like 6 times already, always after 4 hours I can login and ping it...

Try with nf_conntrack.nf_conntrack_helper=0 to disable the helper to see if that fixes it. You might also want to revise the rules in the iptables to use CT instead after that, for more details see http://home.regit.org/netfilter-en/secure-use-of-helpers/
