Comment 17 for bug 1018561

SYMPTOMS: I could not see any packet loss from ifconfig, but I, like others, saw network jitter, latency/ping spikes with continuous pings to www.google.com. Example: http://pastebin.com/J7G3fDnN
(though no packetloss with ping, just the jitter)

SOLUTION (for me):
With latest updates to 12.10 (kernel 3.5) I tried:

Latest drivers from Intel (2.2.14):
http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Network+Connectivity&ProductLine=Intel%C2%AE+Desktop+Adapters&ProductProduct=Intel%C2%AE+Gigabit+CT+Desktop+Adapter

THIS DID NOT FIX IT

Then I added the boot kernel parameters:

GRUB_CMDLINE_LINUX_DEFAULT="acpi=off pcie_aspm=off e1000e.IntMode=1,1 e1000e.InterruptThrottleRate=10000,10000 text"

THIS DID NOT FIX IT

Only after installing the latest 3.7 ubuntu kernel from here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7.9-raring/

Instructions here:

Was my problem resolved.
