I have an Abit KN8 Ultra, nVidia CK804 chipset. I'm having problems with the MAC address on the NIC. Here's how it manifests:
1. networking works fine. ifconfig shows eth1 connected, DHCP works, i see a valid MAC address there, and i'm online posting this message.
2. but: applications that relay on the MAC address for licensing such as Maya, Performer, the CAVE, or other FlexLM-based applications, don't work. For example, when installing Maya, there are no "hardware identifiers" shown to use when requesting a license key.
3. Installing a second PCI ethernet card solves the problem, but for me introduces other weirdness with what looks like IRQ collisions between the ethernet card and my QuadroFX. (see my posts in ../Linux NVidia
i've seen a few other posts that seem kind of related elsewhere, with the solution usually being to just get a new ethernet card. i'm told there is a problem with forcedeth or with the chipset where it returns a bogus MAC address from the actual hardware and then randomly generates a valid one.
Any ideas on how to solve this? here's as much diagnostics as i know to offer:
kernel: 2.6.20-15-generic #2 SMP
output from lmhostid:
The FLEXlm host ID of this machine is ""
relevant line from lspci:

thanks for any suggestions ...
