Effectively I have the same symptoms as those described
in the bug report.

In my case it is annoying but not too much since this machine
is a server which should be always up and always connected.
I have discovered the problem since  it still in the installation
procedure when the switch where it is connected is sometime switched off.

I would be happy however if a patch is published.
