I am running 2 systems using the i7 2600 CPU with the Z68 chip set. Specifically the P8Z68-V Pro mother board. I had been running 6G of memory in each system but changed the configuration after reading this bug report to 8G on 1 and 4G on the other. I am running Ubuntu 10.04.3 LTS 64bit on both systems. Both are behaving the same as the others listed above. They have extremely high latency and very slow file transfers. I am running Intel Pro/1000 GT network cards.
