Public bug reported:
Our server is working fine with kernel release: linux-image-3.2.0-45-generic or
older and with the mainline kernel:
linux-image-3.2.48-030248-generic_3.2.48-030248.201306291335_amd64.deb
But when i reboot the server with Ubuntu kernels: 3.2.0-48 or 3.2.0-49 the
network doesnt work anymore, there are a lot of dropped packets:
