Comment 6 for bug 271744

FWIW: The method to reproduce is simple:

1. Boot with a wired network connection and get an IP. Check the MAC address.

2. Suspend to Ram (using the shutdown dialog and clicking 'suspend' - aka via the menu, NOT through system hotkeys).

3. Resume.

4. Check interface to see if MAC address changed.

5. Repeat.

Notes:

The Assigned (Adam McDaniel) has been able to reproduce this bug himself, but I do not know if he has actual hardware, or if it was a loan unit.

As mentioned, this ONLY affects systems that use the atl1e wired network driver, which should be the 1000H, and the 901. The 900A afaik uses a different wired network driver.

I have had much more success actually suspending using the shutdown dialog than via system hotkeys, and it eliminates any issues that could be caused by the tools that catch/perform the hotkey actions.
