Im having this issue here on two identical SuperMicro X9DBL-iF based
Serves with two Intel 82574L chips each.
Both systems are running on 12.04.2 LTS - Kernel 3.5.0-25 x86_64
We tried so far:
-) applying eeprom fix
-) adding kernel parameters (Kernel 3.5)
-) new kernel (3.8.0-25)
nothing helped, still getting packets "occasionally" dropped - e.g.
stats for one system running for 2 months:
# ifconfig eth0
eth0 Link encap:Ethernet Hardware Adresse 00:25:90:9b:34:70
inet Adresse:10.1.0.2 Bcast:10.1.0.255 Maske:255.255.255.0
inet6-Adresse: fe80::225:90ff:fe9b:3470/64

575.281 dropped are a lot...
Symptoms are:
-) flickering DRBD-link (connection dropped, then resync and back online again)
-) ssh hangs for 1-2 secs
-) ping times > 1 sec
-) various application specific problems due to packet drops
At the moment we don't know what else we could try... - how's the rest
of you going?
