====== forcedeth: random MAC address ====== I got a problem with **Linux kernel 2.6.18** and a **nVidia nForce Ethernet**: the MAC address is not recognized as valid by the kernel an thus a random generated MAC address is assigned: forcedeth: using HIGHDMA 0000:00:0a.0: Invalid Mac address detected: 1d:9b:2a:38:1b:00 Please complain to your hardware vendor. Switching to a random MAC. I seems that in kernel 2.6.21 the issue is solved.
