NIC stopped, pcie_aspm=off

On some newer model Intel NICs they fall asleep at random when using Centos 6.X, or even other OS’s. To combat this, there is a simple addition to the grub.conf that will disable PCIe_ASPM. At the command line enter:

Once in the grub.conf file, insert this into the end of the kernel line:
  • vi /etc/grub.conf

Then paste this code at the end of the line


Exit, save, and reboot for changes to take effect. To check that changes were indeed made, use the following:

  • dmesg|grep PCIe
PCIe ASPM is disabled
