Description Jon R. Kibler 2004-12-12 11:22:52 UTC 
Distribution: Fedora Core 2
Hardware Environment: 3Com 3c556B NIC and IBM ThinkPad A21m (2628GXU)
Software Environment: Fedora Core 2 (Any RedHat post 7.3 seems to have problem)
Problem Description: The 3Com 3c556B NIC breaks 3c59x driver (gives MAC of 
"ff:ff:ff:ff:ff:ff") if ACPI enabled in kernel. Disable ACPI fixes problem. 
(From a Google search, this appears to be a problem in many 3Com NICs.)

Steps to reproduce:
    1. Use IBM Thinkpad w/ 3Com 3c556B NIC and any ACPI enabled kernel past 
RH7.3
    2. boot system
    3. `ifconfig -a` should report MAC address of all "FF"s
    4. edit grub.conf and add "acpi=off" (no quotes) to kernel line
    5. reboot system
    6. `ifconfig -a` should now report the correct MAC address and the interface 
should work correctly
