It's illegal to sell Linux systems without providing or offering the kernel source code, so it usually is available.

OK, yes. Unfortunately it appears that the original firmware does not use a version of mv643xx_eth but a very different driver for this hardware. It is not possible for me to work out what is the important difference between the two. Can you test Linux 3.0 (from testing/unstable) on this system? If that has the same problem then I can ask the upstream developers to help. Ben. -- Ben Hutchings You can't have everything. Where would you put it?
