Hi, I'am siting here for 5 day configuring 4 brandnew Lenovo TS130 Server with
12.10 Server, each having two additional Intel Pro1000GT. Syslog shows that
e1000 drives is used. Interface comes up normaly but shows strange icmp
echo_request (ping ) behaviour.

When I do "ping -v -i 0.2 172.16.0.3" the icmp roudtrip times starts on about
100ms, continously reducing about 1ms every packet until 1ms and then hopp
again to the maximum......scary and strange

Do I see an counter-loop here???
The netwerk performance ist bad too, no wonder.
I changed the NIC, the cable, switchport and switch....still the same. In
addtition a crosslink does not work totaly. I tried normal na cross cable. In
all test mii-diag and mii-tool shows everything ist fine.
onboard nic is e1000e and works as expected, pinging far below 1ms roundtrip.
Do you say that this is a bug or is it a "new" feature I never heard
about and how can I get rid of it.
Thanks for any answers
