I'm seeing the same problem on an ubuntu 12.10 x86-64 server. Random 1 second latencies and /sbin/ifconfig shows the RX dropped packet counter increasing with each stutter/lag.
An example ping:
100 packets transmitted, 100 received, 0% packet loss, time 98995ms
rtt min/avg/max/mdev = 0.255/28.669/1915.588/210.376 ms, pipe 2
I'm seeing a dropped packet every 30 seconds or so.
I've tried the mentioned fixes of turning off ACPI, pcie_aspm and setting the e1000e interuptthrottlerate without fixing it yet.
