Comment 57 for bug 562742

Description of problem:
When I soft-reboot my fedora host the mac addresses change. This machine is:
Jetway J7F2 Fanless 1.2GHz Eden C7 Mini-ITX Motherboard &
Jetway 3xGigaLAN Daughterboard Module

When cold booted, host mac addresses:
eth0 00:30:18:AC:C8:D5
eth1 00:30:18:AC:C8:D6
eth2 00:30:18:AC:C8:D7
eth3 00:30:18:A6:11:E0
(the labels are as discovered on first install)

When soft-rebooted, mac addresses are:
00:00:00:00:C8:D5
00:00:00:00:C8:D6
00:00:00:00:C8:D7
00:30:18:A6:11:E0

OS history - started life as an FC10 last april, has since been upgraded to FC11, then FC12.
First noticed with kernel-2.6.32.9-70 (2010-03-10), but also exhibited it with kernel-2.6.32.9-67 once noticed.

I first thought it was bug 557771, but I now think the NICs are not resetting/initialised/queried properly following a soft reboot.

udev (145-15) went a bit mad and adds pertitent rules to 70-persistent-net.rules which match the mac addresses seen, but using these the driver seems ineffective, it can't see link state changes and tcpdump can't see a thing.

lspci, dmesg, udevinfo attached (cold and soft booted)
