:!: Do not upgrade the Linux kernel. In the new version of kernel-2.6.32-431.29.2 or later, binary compatibility with Kernel ABI is broken and the network driver will not boot after the update. If you already have upgraded, then at the time of solving the problem, please configure the grub boot loader to load the previous kernel version (in the /etc/grub.conf file set default=1).
