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.) Additional problem details can be found at: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=142654 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=107389 (comments 88 & 89) http://fedorafaq.org/fc2/#3c905 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
