After the upgrade, I was encountering a "network unreachable" error. This happens on kernel versions -> 2.6.32-573.1 .1-el6.x86_64 and 2.6.32-573.3.1-el6.x86_64. If I revert back to 2.6.32.504.30.3.el6.x86_64, the problem goes away. I've been searching frantically without much luck. I have found references to the same error on bugs.centos.org but no resolution as of yet. Has anyone else encountered this? If so, what did you do to resolve it?
