RedHat eth interfaces not seem to be present

Dear community,
I'm in trouble with Red Hat Server 5.8. After rebooting the server, I loose two interfaces used for bond2 (eth4 and eth5). I reboot twice the server but the result is always:
Code:
# service network restart
Shutting down interface bond0:                             [  OK  ]
Shutting down interface bond1:                             [  OK  ]
Shutting down interface bond2:                             [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface bond0:                               [  OK  ]
Bringing up interface bond1:                               [  OK  ]
Bringing up interface bond2:  tg3 device eth4 does not seem to be present, delaying initialization.
tg3 device eth5 does not seem to be present, delaying initialization.

Previously I can seen the interfaces under:

Could you please help to restore the eth4 and eth5 ?
Thank you, Lucas

DAMN! Solved! Smilie
I missed HWADDR (MAC) config only on eth4 and eth5... Now tmp device are gone and bond2 is UP!
Sorry for wasting forum space, I hope this can be usefull to someone else, I guess HWADDR must be present on all interfaces! Smilie
