Subject:   dc NIC: mac address gets reset (5.0-REL)

I just installed FreeBSD 5.0-RELEASE on a machine that was running 4.7-RELEASE-p3 before. I've got a problem with my network card:

After rebooting the system, it's MAC address is reset to C0:00:C0:00:C0:00. The card works fine otherwise (apart from some "dc: failed to force tx and rx to idle state" messages that are, as far as the mailing lists tell me, uncritical). This of course makes the DHCP server give me another than my standard IP. Also, if I install FreeBSD 5.0 on another machine in my LAN, and it shows the same behaviour, i'll run into problems.

I can manually change the MAC address back to its old value, then restart dhclient, and it works. However, I don't want to have to do that after every reboot...

Here's the relevant lines from dmesg:
----- PASTE START -----
dc0: <Davicom DM9102A 10/100BaseTX> port 0xd000-0xd0ff mem 0xef000000-0xef0000ff irq 11 at device 11.0 on pci0

----- PASTE END -----

Any ideas?
