A possible firmware problem with the Broadcom BCM5702
Gigabit Ethernet adapter on the mainboard causes problems
with the MAC address.
The ethernet adapter may have no MAC address which causes
problems in the local network and does not work with Eloquence.
Depending on the model, the MAC address is never present
or disappears after a reboot.
This has been observed on different systems, such as
the HP/Compaq Proliant ML310T01 and ML350T01 or the
HP TC2120.
Workaround:
- Power-cycle the machine
- Write down the MAC address. If the MAC address
is never available in Linux, plase go into the
BIOS.
- Add the MAC address to the /etc/modules.conf
post-install bcm5700 ifconfig eth0 hw ether MAC_ADDRESS
