Since upgrading a CentOS 6.4 with a SuperMicro X8SIE-F/X9SCL board with Intel 82574L NIC to 2.6.32-431.el6.x86_64 and rebooting, I have been having consistent NIC failures where the NIC shuts down permanently until a soft reboot is performed.
Type the following commands to get more info about error

I found the following conversations on the net, exactly the same situation:
https://bugzilla.redhat.com/show_bug.cgi?id=625776 https://lkml.org/lkml/2012/3/17/48 http://lists.centos.org/pipermail/centos/2011-September/118027.html http://sourceforge.net/p/e1000/bugs/358/
A quick step to fix this problem
Step 1. Login SSH as root
Step 2. Add pcie_aspm=off kernel parameters to grub config
# cd /boot/grub # vi grub.conf
Find and add “pcie_aspm=off” at the end of the kernel parameters

Step 3. Save and reboot
# shutdown -r now
