In 2.2.13 a bug in the packet scheduler was fixed which caused a first packet
only being sent out when a second has to be sent out. Maybe the bug was not
fully ir incorrectly fixed? Knowing if 2.2.12 or one of the kernels you
sue fix the problem would be helpful to know. For what it's worth, this is
the change in the packet scheduler which has been done in 2.2.13:

                }

The problem fixed by this change was known as the multible-second ping time bug:
You started a ping with one second interval and you got ping times of 1,2,3,4,5
seconds+the usual delay of the network.
