After a soft reboot (using the "reboot" command), the system cannot get an IP address using DHCP. On the console, a MAC address of 00 00 00 00 00 00 is shown. When rebooting with "reboot -f" or with the reset button, everything works as expected. This used to work, and broke between 2.6.16 and 2.6.17. Using git bissect, I could trace this back to that commit: commit bc1c756741b065cfebf850e4164c0e2aae9d527f Author: Michael Chan <mchan@...adcom.com> Date: Mon Mar 20 17:48:03 2006 -0800 [TG3]: Support shutdown WoL.
