Software Environment: Kernel 2.6.20.7
Problem Description:

Sometimes the network behind Marvell Technology (sky2) stops working. A LED
indicates that it's up and receiving packets but no packet can actually pass
through. arping the nearest router gives no response.  Kernel spouts no messages
in such cases. It's strange but ethtool eth1 also says that the network is up
and running at its full speed. rmmoding and modprobe'ing sky2 module solves this
problem.
