Comment 7 for bug 42572

I have the same alternating latency problem on my Thinkpad T60. It uses the e1000 driver as well. When I ping the Thinkpad from another host on my local network, the ping-times alternate between one second and a few milliseconds, almost always in the sequence long, short, long, short etc. I have tested this with both 6.06.1 and Edgy Eft Knot 3 with the same result.

The long latency makes remote X and ssh very painful to use, since the network seems to freeze one second at a time.

This problem has been reported in the Kernel bugzilla: http://bugme.osdl.org/show_bug.cgi?id=6929
